Removing the fuse for a few minutes and turning the controls on both driver side and passenger side to the highest setting and then turning them down slowly until the system started cooling has worked for me. Thanks for the suggestions---saved me $2500.00 on a useless dealer estimate to fix problem. These dealers are dangerous---they were the ones that caused my problem when they unhooked the battery while replacing my ignition switch.
This is a good forum.

U have a stuck air temp control blend door, either the actuator motor is defective or the door is warped and has jammed, one thing is that u must remove the dash to rcheck replace these parts.

I would first check and make sure that you have enough Freon in the system, on climate control dual systems only one side will put out cold air if the system is low on Freon. Eventually, both sides will put out warm/hot air if the system continues to loose Freon. As with all leaks the system should be checked and then the leak causing component replaced/repaired.

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck
