What to do if your heat control is not working?
Connect a vacuum pump to the function selector switch vacuum harness connector and try to pull a vacuum. If the pump can pull and hold a vacuum, the hose is plugged. If the pump pulls a vacuum that slowly decays, the hose is restricted. Is the hose plugged or restricted? Yes REPLACE the vacuum hose. TEST the system for normal operation.
How to troubleshoot blend actuator without climate control?
NOTE: Before testing the motor, check for HVAC DTCs See: Heating and Air Conditioning > Initial Inspection and Diagnostic Overview > How To Troubleshoot The Heating And A/C Systems (Without Climate Control). 1. Disconnect the 7P connector from the air mix control motor.
Is there a way to change the temp on a blend door?
Yes GO to E11. No REPAIR Circuit 359 (GY/R). TEST the system for normal operation. Measure the resistance between the temperature blend control connector Pin C231-2, Circuit 773 (DG/O), and the blend door actuator connector Pin C240-3.
How to diagnose blows cold one side, hot on other side?
So your first step in diagnosing a blows cold one side, hot on other side condition is to operate each temperature control to see which side changes temperature. The actuator that changes temperature is good, the actuator that doesn’t is bad. This test also proves out the HVAC controller.
What to do if your climate control is stuck?
This initiates a re calibration of climate control equipment and actuators. It will fix your problem. You can’t post conmments that contain an email address. My passenger seat is stuck in recline.
Why does my HVAC blow cold air and hot air?
Drivers changed air temperature far more often than they change the mode (defrost, floor heat, dash vents, etc.), so the temperature actuators generally fail first. When that happens, the HVAC system can be stuck on blows cold air or blows hot air. In a dual zone system, you wind up with a blows cold one side, hot on other side condition.
Can a car vent blow cold one side and hot the other?
In a vehicle with dual temperature controls you may encounter a situation where the vent blows cold one side, hot on other side or vice versa.
