another issue with my 95. was hoping for a little more of you guy's diagnostic expertise, i have had issues also with my heat/ac for sometime now. It sounded like a bomb ticking in my dash for the longest time, and was stuck on full blast heat, no matter what button i push. if its really cold out, the ac is stuck on , but when its hot, the heat is stuck, not even vent from outside air...just full blast cookin heat, i can adjust my fan speed still though. i know has to be some kind of flapper in there, but just what? any info appreciated
