Re: C68 HVAC Programmer Compatibility for 1990
When you put it together and turned the key for the first time did you wait until the blower went to full speed? As I recall the blend door needs to calibrate before using the unit. You need to do this every time you disconnect the battery as well.
Off question, what is the color combo of your 1990? My buddy had a 1990 and we swapped the programmer for a 94-96 unit and it worked fine. He has since sold it and it changed hands a couple times, maybe that is the car you have now
