Repairing HVAC Fan Motor Resistors / Blower Motors

HVAC Fan Motor Resistors

HVAC Fan Motor resistors are responsible for controlling the blower motor speed. They do this by varying the voltage supplied to the blower motor. They are prone to shorts, corrosion, and overheating. When the resistor fails, typically, the highest setting is the only option that still functions. 

When replacing your heat, A/C, & ventilation blower fan motor or HVAC van motor, we always replace the resistor. We do this due to the potential that the old resistor may damage the new motor. We also replace the inexpensive relay just to ensure that you HVAC motor will not prematurely fail and that you’ll always have air flow though your HVAC system.

Some Blower motors look like this and need assembled inside the blower motor housing.
Other fan motors, mostly on modern cars, come like this ready to install.

Another reason your fan motor might not be working is the switch on your dash. Although very unlikely, we have seen these fail on some cars. Vehicles with more modern digital temperature controls are a little more complex. These digital controllers are also known to fail, however diagnosing the problem is sometimes a little easier. Using a OBDII factory scan tool, we are able to scan the entire vehicle for fault codes. The HVAC system will typically tell us what to look at, although it never says, “replace this part”. We would have to manually inspect the components related to the fault codes and identity the exact problem.

Sometimes performing a service on your air conditioning system will fix the problem. Systems that have leaks and are low on refrigerant will not function. Other times too much pressure will cause it not to work as well. One thing we see a lot of is people trying to charge their own A/C systems with a over the counter bottle. This is by far the best way to damage your A/C system. We see more damage to A/C systems cause from owners thinking they can fix it with a bottle for $25. In the long run you might pay hundreds, if not thousands of dollars to repair this. Over pressurizing the system will damage sensors, pumps and expansion valves. Bring it to the professional with the correct A/C service machine and avoid costly repairs in the future.

Project 1991 Mercedes-Benz 560sec

,

Project 1991 Mercedes-Benz 560sec

It’s been a long road to completion but we finally got Project 1991 Mercedes-Benz 560sec finished today. Our customer came in about 6 months ago wanting to do a air suspension install on his 1991 Mercedes-Benz 560sec. We wrote him a quote based off his needs and some suggestions from Meister Werks. After approving the quote we ordered all the parts necessary to install his custom setup. The customer also wanted us to have the bumpers, side mouldings, mirrors and door handles painted white to match the body. We contacted our friends at Automotive Solutions to come out and do all the body work, prep and paint.

Fast forward a few weeks later, Covid-19 / Coronavirus hit the Seattle area and thus started the parts delays. It took a few months of waiting to get all the parts in. A few months later in March, we finally received everything and the install started very soon after. We also installed a kit on this customer’s 1990 Mercedes-Benz 500SL, which can be seen by clicking here.

The Install Begins

We began the install by removing the bumpers, side mouldings, mirrors and door handles. While these parts were out, we started polishing the OEM stainless steel trim. After all the parts went into paint, we began the air suspension portion. We started the air system by disassembling the custom stereo setup in the trunk. The car stereo installer had fabricated a custom enclosure to house the rose gold plated air tank, Air Zenith air compressors and Airlift 3p manifold. We bent custom hard lines, powder coated them white (to match the body) and affixed all the fittings to the components.

After we did this, we installed them into the custom build enclosure. Additionally, we wired the Air Zenith OB2 compressors with 4 gauge wires and 80 amp fuses. Futhermore, we ran the custom harness to the Airlift 3p manifold, then connected the remote wire to the ignition circuit. Once that was complete, we installed the 3p controller in the Mercedes-Benz 560sec center console.

Air Suspension Issues

We had many issues with the custom air bags we purchased from a company in Germany. The bags were rubbing on the body and the upper bag mount did not line up with the control arms. Countless hours corresponding, assembly, disassembly, reassembly, photos and diagrams were sent to the manufacturers. After weeks of communications, we finally got results and newly machined parts were shipped from Germany. After 3 additional weeks, we received new parts. Unfortunately the parts still did not work right. So we decided to machine the new parts in house to get them to work. What we machined was perfection and will be able to replicate this on any future projects. This Mercedes-Benz is now able to air up properly, lay frame and not rub on the body. These additional modifications to the air suspension were much better than the original kit.

 

More Custom

We also had to delete the Mercedes-Benz factory hydraulic suspension. To do this we removed the rear shocks, removed the hydraulic pump on the engine and machined a custom block off plate. We used 6061 T6 aluminum to machine this part in our inhouse machine shop. We also made a custom gasket on our CNC laser cutter. Everything installed perfect, with no leaks or issues.

 

Wrapping it up

With the components installed, we attached the air lines using OEM brake line clips to secure the air lines in place. While all this work was being done, we assembled and sealed the wheel. These were custom plasted rose gold on the AMG monoblock wheels. After sealing these three piece wheels, we mounted and balanced the tires. After test fitting the wheels, we knew we needed spacers on the front. To give this beautiful Mercedes-Benz 560sec a flush fit, we installed 20mm spacers all the way around.

After all of this hard work, we finally were able to test the system. We checked for air leaks, buttoned up the trunk, and make sure all the small details were ironed out.

Code, Update & Program Control Modules

Coding, Updating & Programming Control Modules

Meister Werks now has the ability to code, update & program control modules. We can fully scan your BMW, VW or Audi and verify that the control modules are up to date.

The manufacturers regularly update software that is necessary for a efficiently running vehicle. When cars are first manufactured, the parameters are written for very tight tolerances. As the cars age and parts start to break in, some parameters can slightly shift out. This can cause check engine lights or components to no longer function. Often, this does not mean than the part is faulty, the software just needs updated. Just like your laptop computer or smart phone.

2006 BMW M6 V10

In the case of this 2006 BMW M6 V10, there were many modules that would not function even after we replaced the faulty components. The communication between modules would no longer talk to each other. After scanning this BMW with our new software, we found many modules were out of date. After performing an update, the car ran and sounded much better. The steering column switch that failed, now is functional. The software will also tell us if there is a faulty component, a wire short and where the location of that is. This makes diagnosing you vehicle much quicker and the result is a potentially smaller repair bill.

In this instance, the screen shot shows the version ID from BMW’s plant in Munich, Germany (outlined in red) is much older than the software on the vehicle. Our software connects directly to the manufacturer, insuring the most up to date software is loaded onto your vehicle. This will update everything from engine control modules and transmission control modules to the radio, battery control modules and even the instrument cluster.

More Info

If you have any questions about this service, feel free to contact us any time for a estimate or an appointment. To make an appointment for your vehicle’s coding, updating & programming control modules, call 425-254-0627 or email us.

Porsche 911 / 996 Headlight Refurbishing

Porsche 911 / 996 Headlight Refurbishing

Our customer brought in his set of Porsche 911 / 996 Turbo for headlight refurbishing. The lens were oxidized and dull when they arrived. This is cause from the sun light’s UV breaking down the surface of the lens. We wet sand all the contaminants out, clean and spray with our special clearcoat. This clearcoat is the same acrylic makeup as the lens which bonds with it down to the molecular structure. Not only that, but the clear coat adds a layer of protection against fading or oxidation. The clear coat also dries very glossy and there is no need for wet sanding or buffing after the clear coat dries. However, we can do this and is an additional option if you upon request.

Note: Some imperfections are within the inside of the lens area and are unable to be removed. New housing would be an alternative to getting brand new headlights.

Powder Coating Harley-Davidson Parts

Powder Coating Harley-Davidson Parts

Our long time friend Pete came in last week for powder coating Harley-Davidson chrome parts for his motorcycle bike. Since we can not powder coat directly over chrome, we knew we had a challenge.

We would need to etch the chrome in some way for the powder to stick. We ended up media blasting the chrome with 34 grit aluminum oxide. This takes about four times longer than any other material to etch.

We set up our automated media blaster with rotisserie to blast his items for about an hour. After that done, we did touch ups for around 30 minutes to get everything even and etched properly. We then cleaned and prepped the surface throughly and hung the parts for powder coating. We use Cardnal Industrial Finishes, BLACK Super Durable 90 Gloss, color code P009-BK180. This extremely glossy powder will withstands the riggers of the road and lasts five times longer than any other powder. As you can see the finish and the glossiness is pretty amazing.

To make an appointment to have us do powder coating Harley-Davidson parts, call 425-254-0627 – Ex 0, or email us. Meister Werks European & Import is located one block south from The Renton Landing in Renton, WA.

Mounting and Balancing Tires on Flat Lip 3 Piece Wheels

Mounting and Balancing Tires on Flat Lip 3 Piece Wheels

We regularly receive jobs in the shop for mounting and balancing tires for flat lip, 3 piece wheels. This can pose a challenge as the back barrels do not have a drop for us to dismount the tire properly.

When performing this service, we have to remove the face side tire first. We always use the Motion Pro Rim Shield guards to protect the wheel lips. After that, we remove the tire from the machine. Using the bead breaker, we push the rest of the tire off into the tire well or tire drop portion of the wheel. Once this is achieved, we return the wheel and tire to the machine and remove the rest of the tire. Mounting can also be challenging, but in this video instance, there was not a problem. People with stretched tires will have more issues getting them to bead on the wheel lip beads correctly.

Even though this video is sped up, this requires more labor to remove the tire. We charge an hourly rate for all custom 3 piece wheels. If you have a standard wheel, made by your vehicle’s manufacturer, there is no need to worry. There will not be any additional charge for standard wheels.

With a purchase of tires at Meister Werks, we also offer free flat repair, free tire rotation and we will warranty your tires if there is a warranty issue with the manufacturers milage warranty. Anther service we offer is wheel alignment. On our state of the art 3d laser alignment machine, we will be able to dial in your alignment. This will eliminate unnecessary tire wear and prolong the life of your tires.

To make an appointment to have your tires changed, call 425-254-0627 or email us. Meister Werks European & Import is located one block south from The Renton Landing in Renton, WA.
