    Product Seems to Work Well

    A bit of a pain to change in my 2000 Corvette. No fault of the replacement part - it's due to the design of the 'vette.

        Comments about Dorman - OE Solutions HVA/C Air Door Actuator:

        This is a pain to install, but easier than the passenger side controller, and that is the fault of GM engineers and GMC's failure to prevent putting parts in they should have known would fail. It eliminated the driver's side from going to full heat when he air conditioner is on. Now all I have left is to completely disassemble the dashboard to replace the passenger side.

              The part is easy to install when you eventually gain access....these are typically not in the easiest locations to reach. My vehicle needed 2 replaced but i did all three because i had the entire dash board apart. Be carefull not to bend the electrical connection pins when pushing on the connector.

              This model is expensive compare to similar models.

              Other than gaining access to the actuator (blame GM) it fell right into place. This is the second one I've had to replace and by far the most difficult. I think there's only two more!

              Exactly like the original part. A/C blend door works perfectly now. No more Hot Air blowing Randomly anymore. The Part goes in easily, but the cover is tricky to install. Nothing that someone with minimal mechanical abilities can't handle.

                  This is the part that fixed the infamous Avalanche hot air AC condition. Its a little difficult to install due to the tight spaces but can be done in less than an hour. After installing you will have to run through the calibration procedure. This consists of removing the climate control fuse under the hood for at least 30 seconds, then replacing it and starting the vehicle back up without adjusting any of the temperature controls. As a side note, after installation I noticed that air would only blow through the defroster eventhough the dash or floor vents were selected. This lasted for about 2 days until it went back into normal working order.

                            Hi Eric, glad to assist you! There are several reasons your vehicle may be blowing hot air through the vents, such as a need to recharge refrigerant. There could also be a problem with the air conditioner's compressor. Vents will blow hot air if the compressor does not activate when the A/C is turned on. To find out if the air conditioner's compressor is causing hot air to come from your vents, you can test it by connecting its clutch wire to a battery. If the compressor fails to turn, it is likely that you will need to have it replaced. If your air conditioner is low on refrigerant, it can be recharged to combat this issue. However, checking for leaks should always be done before taking this action. Also, your air conditioning system's vacuum should have all air removed from it prior to recharging refrigerant. I would suggest that you to take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

                            Hi Matt, glad to help you! Your Cadillac Seville uses a separate blend door motor for each side of the front passenger compartment. My first step would be to put my hands on these actuators and see if they are moving at all in response to commands. Sometimes, if they don't move, you can give them a light tap with a screwdriver handle or something similar, and they will come to life, if only temporarily, but that will help you pinpoint the cause. There are scan tool diagnostics for this, I would make it my second step to attach a scan tool, command these actuators manually, and see if the voltages respond to commands. But honestly, you'll probably find that giving them a tap-tap is a faster way to diagnose the actuators.

                            Allow the engine to reach normal operating temperature. Set the function selector switch to the MAX A/C position. Adjust the blend door potentiometer to full COOL (left) and check for cool air discharge. Adjust the blend door potentiometer to full WARM (right) and check for warm air discharge. Vary the blend door actuator control from full WARM to full COOL. If the air temperature changes, then the system is OK. Or else check with the fuse and check the voltage to the a/c electronic blend door actuator motor. For any further assistance, please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.

                            The actuator could possibly be the problem. However, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest that you take your vehicle to a certified mechanic for further diagnosis.
