The other day I had a problem with the perimeter alarm and PATS weren't working and immobilized my 02 Sport. Our resident expert Joe helped me figure it out. Thanks again, Joe. Upon going to work the next day which it had warmed up I discovered a new problem. In addition to my driver's door lock sticking (have no idea why since it wasn't before the alarm problem) and the traction control light flashing (which it was solid before the alarm problem even though I'm not getting any codes and it is working), I now discover the AC isn't blowing cold anymore. I understand when that happens it's almost always the DCCV but I'm wondering how I would test it. Forscan isn't showing any error codes when I run it's EATC test so I'm not sure where and what to check other than the DCCV which I don't know how to check that. Can anyone advise me?
