A/c is blowing very hot air from just two vents on the front right side of vehicle. all other vents blow cold air. This started right after i had my battery changed
You may have to have the body computer "flashed" by a dealer scan tool. Sometimes the body computer looses data when the battery is disconnected. Sometimes it relearns itself after a few trips.
SOURCE: A/C blowing hot air, I'm testing your talents because so far this site has done me no good
Run the OBD diagnostic with the ATC self test feature. I bet you'll find a faulty blend door or motor....accordianman PS Three Pounds??!!?
SOURCE: driver side ac not cold
It is not a coolant leak. Nice try though. It is possible that the infra red temp sensor is faulty, also it may be a mode door(directs air flow in the heater box) or a mode door actuator. Your dealer can test for proper door actuation, and can also check temperature difference, some is not uncommon, but it depends on the temp setting, is this a dual zone, or tri-zone atc unit?
SOURCE: Heater only blows cold air
Check both heater hoses under hood to see if they get hot, if they do the heater is fine. need to check to see if the selection doors inside the unit are opening and closing.
SOURCE: Heat on, blows cold air on passenger side
u will need to repair the passenger side air temp control blend door, either the door is stuck or the small electric actuator that moves it is defective.
