I might have a similiar problem (I think)...
My air is stuck on Defrost only. Both cold and hot air works and variable fan speeds work as well but I can not get the air to blow out of the front vents.
Please advise if I have the same problem? Thanks a lot in advance!
Also, sorry, but I am not mechanical. If my problem is the same as this one, could instructions on how to do these task be posted here or emailed to me? I am not afraid to try and adjust/fix it myself. I don't think $1,000.00 + to take off the dashboard that the dealer suggest as a first option is what I would like to do.
A friend suggested a clothes hanger solution was on the internet because some "flapper" was stuck...not finding that solution viable.
Two causes, vacum and the cable behind the contols, pretty easy to fix. On the 97 and 98 it maybe a small $15 dollar pin that entails an $800 labor charge, the pin is in the heater box so it's the same as replacing the heater core or the evaporator. I don't think the pin holds true for the newer one, they supposedly fixed it with a steel pin vs the plastic one in the older models but I could be wrong..
i fixed it, it was the vac line on the drivers side of the motor. its popped off. took me 30 seconds to fix
