I replaced the blower and speed control module and the blower now works perfectly. Unfortunately the AC no longer works but I can hear the compressor kick in. Sigh.

I finally got the time to do some more testing. With the blower connected or not connected there is battery voltage at the connector. The voltage does not change if I change the speed on the controller. I will order a new blower and perhaps the control module as well. What's your opinion?

I have not been able to determine the cause of the blower failure and have decided to try and replace the most suspect part or parts. Before I remove the blower motor again I was hoping someone could tell me where the speed control module is (resistor). This is a dual zone climate control auto...

No HVAC codes. There is no way for me to check the voltage to the motor while it's connected. Besides. The motor worked at length on the bench and for a few seconds installed so I have to assume if there is voltage to the motor in the car it should work. The connector is tight and snapped in to...

I posted here a while back about a problem I was having with the blower with the climate control. I took the blower out again and did some testing. I bench tested the blower and it works fine. I checked for voltage at the blower connector and it's 13.2 with the engine running and the A/C on. I...

No, I do not. I did look at the DIC codes for the car though and it shows "99 HVAC No Codes". All the other codes were (H)istory. There are no active codes. I am considering resetting the HVAC unit by removing fuse 27 (I believe ) under the passenger side floorboard. One other strange thing...

This is a tough one. My 2001 C5 that I purchased almost 20 years ago has been sitting mostly idle for several years. It runs perfectly and I do drive it occasionally but health conditions related to my wife prevent me from using and enjoying it. It has 35,000 miles on it now and for the...
