I've been reading every post I can find here on Gen 1 climate control issues. So far this is what I think I know:
* There is one a/c system that feeds both the passenger and driver sides
* Each side has its own heating system, controlled by the DCCV valve
* The system controls the temp on each side by blending a/c air with each side's own individual DCCV air
* When the system is placed on 60 degrees "Max Cool", there is a bypass door that opens/shuts to block off any potential hot air blend from the DCCV
* DCCVs get stuck a lot on these cars
* DCCVs can be cleaned instead of replaced (Tireman's instructions)
* The system has a self-test mode that is started by pressing "OFF" and "DEFROST' and the same time, then pressing "AUTO" within two seconds
I showed no codes when I ran the self test.
However my situation is confusing me. When the a/c is running, the driver side gets cold air but the passenger side gets warm air. Even when I crank the temp down to 60 degrees, still warm air from the passenger side.
Question 1 - If the bypass door blocks any hot air from being used, how can I still be getting warm passenger side air when temp is set at 60 degrees?
Question 2 - Does this sound like my DCCV valve is stuck in the OPEN position on my passenger side?
Question 3 - Am I missing something here?
Thanks for your feedback!
