I am in a same boat! Any solution for the fix? I recharged the freon yesterday, but still got the warm air coming out from the middle vent (only on the driver side) I can heard the vent fan running even though my heater is NOT turn only! Any idea? Thanks

BUMP!!! Having some issues with the ac blowing warm air.

Would a bad thermostat be a possible cause? My heat works poorly in the winter...

A member just messaged me asking if I ever got this resolved. I still have the car, and I still have the problem. I'm posting this here in the hopes someone did actually get this fixed and can provide the details as to what the problem/fix is. Below is my reply that had a few more details as to what I attempted:

"Nope. Still have the car, still have the problem. Since that thread, I did end up pulling the dash out and checking out all the actuator and flaps (or so I thought). As far as I could tell, all the actuators I could SEE were working as expected. The only thing I found, and I was thrilled as I thought it must have been the issues, was that one of the two flaps located in the firewall (don't recall which side) was open while the other was closed. It's been so long, so I can't remember if that one was stuck open and never moved, or if it moved opposite the other side. I seem to recall that it was stuck open. So I was able to separate the piece that moves that flap from the actuator that controlled it, changed the AC to heat, so the flaps opened, and then connected it again so both opened and closed at the same time. I suspect the one was stuck open/disconnected from the actuator during the time I had the dealership replace the leaking evaporator coil. I'm guessing they didn't put it back together properly or didn't pay close enough attention to the details. So thinking I had to have fixed it, I closed it all back up, put the dash back in, took it for a test drive, and realized the problem was not fixed. The only other thing is that there were two actuators that were not accessible without taking out the entire plastic AC housing - I believe they were located at the back of the housing, so I didn't actually check those two actuators and associated flaps. I'm GUESSING that's probably the issue, however I seem to remember getting that AC housing out from behind the frame support bars was going to be a huge pain. I'm going to post this back in that thread in the hopes that anyone who had the same problems we do can post what the actual fix was. Please - if you do get this fixed, let me know the details as this is the only issue I have with my car and it makes summer time pure hell."
