Dissconnect the battery for 1 hour and reconnect, should re-set the flaps!
Temp blend door actuator malfunction.
When my a/c system is low on refrigerant, it blows hot on drivers side, cold on passenger side of the dashboard. This is a 1997 Buick Ultra. Recharging the system solves the problem.
I have the same problem with my 95 olds 98 regency, did you find anything out?
heater control valve is bad on the drivers side.
My 1998 Intrigue did the same thing after battery was replaced. Found the answer online. Turn the AC and car off, disconnect the battery, wait 5 minutes, open both front doors, reconnect the battery, start car, turn on the AC full cold. This resets the computer and the AC works perfectly!
Your average A/C unit blows heat through all vents.
i just got i back from getting a wiper switch installed and this started happening the day i got it back. so could they have messed with something or what help please cheese problem go to a macanic it well help alot
they ignite the ignition and blows up
yes if it blows up though its not my fault
I had that problem too. when I checked my freon, it was low so I recharged it and was able to get cold air back on drivers side. then a month later, the seal went out on my AC compressor. So I would guess your freon is low and AC compressor is (or is about to) start leaking
make sure both knobs are all the way up on red for heat...
usually system is low of freon when this concern occurs. if 134 freon is ok then temp doors may be out of calibration. djones1
