98 SSEi Automatic Climate control issues
A/C stopped working in the fall. The heater seemed to work ok over the winter without the A/C. This spring I noticed that even with the Climate Control turned off I was still getting warm air thru the floor.
Took it to my mechanic. He said the compressor was shot and the programmer was not working right. He recommended not fixing it since the car is so old and has 200k miles on it. (He is not a member of this forum and apparently he does not know a true Bonneville fan never surrenders).
I told him to replace the compressor and I would take care of getting a programmer. When I left his shop cold air was blowing out the defroster but I could not get it to come out the dash vents.
I bought a used programmer and installed it. Wham! just like that I have air coming out whatever vent I desire! Wait not so fast! The air doesn't seem to be as cold as it should be. ??? Go read the forum. Could be the actuator. Sure enough the blend door is not moving. Take it all apart again remove the actuator , disassemble it. Sure enough the plastic gear in the actuator is broken. Call Rock Auto, get and install new actuator . Sure enough programmer moves actuator back and forth as it should , problem solved!!
Not so fast! the temp light flashes for 60 seconds when I turn it on and the compressor does not seem to come on. Took it back to the mechanic to see if it is properly charged. He checked the Freon looks good. He removed the battery cable for a minute to reset it and boom! it works great, cold air comes out any vent that I desire. The next morning no cold air and the temp light is flashing again. Okay back to the forum. I read every post on the subject back to 2009. Swapped the exterior temp sensor with the one in the Park Ave ( known good part) . nothing changes. Take the dash apart and clean the interior temp sensor (it was filthy, that'* got to be it!) Still no change. Its a good thing I love this car because otherwise I would not be posting here I would be calling the wrecking yard. If any of you has an words of wisdom I am all ears. Thanks
