Auto Climate Stuck In Defrost Mode
Posted 29 November 2007 - 10:55 AM
I also noticed the AC comppresor clutch is not engaging.
I did some resaerch and found this sevice bulletin, 04-01-38-008 dated 6-17-2004.
It know it may be just a coincidence regarding the battery connection, but it did work fine untill then.
I also switched out the AC relay under the hood and it did not help.
Any help on this will be greatly appreciated.

I also came acroos this service bullitin #04-01-38-008 dated 6-17-04. Service buletin states wireing harness behind guages is to short and causes HVAC to go into a default mode (defrost only).
I am also going to investigate this bulletin if the battery trick does not work.

If anyone cares to know, I fixed this problem by locating and unplugging the blend door actuator.
The actuator motor is located behind the lower center dash, over the tranny hump, and accesed from the drivers side.
