99 BLOWS HOT AIR
1999 Chrysler LHS • 6 cylinder 2WD Automatic •
I have a 99 Chrysler LHS. When you turn on the air conditioning it (might) blow cold for a few minutes then it will start blowing hot - really hot air. MOst of the time it just blows hot. Car is not overheating and the coolant is up to correct levels. The compressor is working and you can tell by feeling the evap line that it is cooling. Even checked the system with gages and the levels of 134 are correct. It just blows hot air all the time. Is there a switch or flap that is failing causing it to change from air to heat??
Does AC control look like diagram?
Yes that is it exactly. As another note. If you switch the position of the air as it should come out of the vents or the defrost or down at your feet all this works. Any ideas??
Trans in Park start engine set ACT to 75.Turn blower motor selsctro counterclockwise to off.Simultaneously press and hold floor ,mix and front defrost buttons.Release when ATC begings to blink system will calibrate blend doors. If O.K. ATC return to normal operation anf "F" "C". If DTC's are present they will be displayed in two digits. Press MODE button to scroll then post codes
Ok Im going to go do this now. Any other suggestions after this. Could the ATC control be bad??
Did exactly as you asked and the air is staying on now and is nice and cold. Thanks for your advice. Worked great!!
Keep info may happen again common fault
Got it saved. Thanks again.
