Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).
The fix: Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process. In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.
If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.
sounds like a leak. Have your system checked for leaks and re-charged. If the system is full of refrigerant, then check the pressure switch on the compressor and the pressure switch on the accumulator (dryer). If the pressure in the system is low, these switches prevent the compressor from running to prevent damage.
I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?
there should be some aluminum lines under the truck on the rear of body, feel these lines with the a/c on, if they are cold then there is something wrong with your rear blen door, blend door is the door controling the cold or hot desire position, sometimes it is controled by vacium and sometimes it is electrical, if lines are cold what most likelly they will be then have the rear belnd door actuator inspect.
