Just found this forum and glad I did, as I already have used the advise/suggestions posted by headhunter? (If I go back to find that person, I'll lose where i'm at, never to be found again!) I don't remember who, but gave very good inst. My problem is, after changing the blower motor and resister, the veh stays in the defrost mode and the 2 little lights on the press buttons, blink all the time. I installed a new ac compressor, blower mtr and resister, which was not much PITA, after all. PLEASE, if you know/think you know/educated guesstimate let me hear from you and THANK you very much!
