Hey all... after having recently replaced a power transistor to get what I thought was a blown blower ($$$$) I thought that my winter heatwoes were solved, now that the air was back to blowing... But when I start it up, the temp display works fine, I can adjust the temp no prob. Minutes later I see the temp display go from what I set it to, to flashing "08" then the original temp I set, then "08" again! And I hear the vent door motors start actuating, but NO heat comes out. Just ambient air. I've tried looking everywhere for what this "08" means but I cannot find any info. The guy that sold my Pop's the car told us it was a temp sensor, namely the one in the main vent... so I disassembled the whole dash, found it and tested it's resistance with a voltmeter. It increased /decreased resistance as it should when I would blow warmer/colder air on it. So I know it's working fine. I also tested the other 2 sensors; the one on the inside of the car and the one right above the power transistor I replaced. Both or should I say all 3 are working fine! Does anyone have any suggestions? I REALLY need HEAT! Thanks.
