So I bought my '96 Talon eight years ago with a broken A/C, and with the recent wreck and probable total loss of my '97 daily driver DSM--just as oppressive Florida Summer begins, of course--I'm trying to diagnose and hopefully get the air in the '96 blowing cold again.
Same Symptoms have persisted throughout my ownership of the car: when I turn the blower on and hit the a/c button, the green light illuminates and stays steady, but the compressor clutch cycles between engaged and disengaged endlessly. At one time it'd blow cold(ish) despite the cycling, but these days it's like an angry drunk is breathing hot air on my face when I switch the a/c on. I also noticed that the green light didn't illuminate once or twice when hitting the compressor switch, a symptom that seems to have developed while the car was sitting these last years.
I tried bypassing the dual-pressure switch with no change in the symptoms; I tried replacing the a/c controller on the evaporator with one from a parts car with no change, nor when I jumped the connector terminals for the a/c controller. With no A/c controller attached, the compressor doesn't engage (obviously).
Here's a video of the compressor cycling:
Any Ideas?
