Blend door problem
Climate Control System won't heat car.
System is stuck in "COLD" mode. Regardless of temperature I set, it blows cold air.
I never use the "AUTO" feature. I always use the manual method of setting temp and fan speed.
I replaced the Blend door motor with a new part from dealer.
I just replaced the control panel with a used part.
Diagnostic codes with ORIGINAL control panel:
36 ATC Head Communication Failure
23 A/C Blend Door Feedback Failure
26 ATC In-Car Sensor
I disconnect the negative battery cable
and install the USED control panel, reconnect battery
and the temperature on the overhead console reads 75F (its about 52F outside)
Same problem (no warm air) but I only get a code 23
If I connect the blend door motor, but let it hang down so I can see it turn, it moves a good deal when I run diagnostics, but when I try to set temp to LO or HIGH it barely moves. (With either control panel)
While the motor is off, I can move the door until I hear it "SHUT" and then I get HOT AIR, so I dont think the door itself is bad.
Where do I go from here?
This is frustrating!
have the same problem?
