After replacement new battery about 2 months ago, my 2003 XC90 T6 CCM has following problems:
(1) fan is start up at max automatically when start the car
(2) A/C has not cold air, always blowing warm air

I had transmission replacement 1 week ago, he found climate control module error code before transmission replacement check, but did not tell me what kind of error it is, and ask me to bring it back for 1 hour diagnosis.

I tried to disconnect battery, put (+) and (-) cables together for reset CCM, but not work.

Any hints for this issue? compressor, clutch, freoz problem, reprogramming CCM, or replace CCM?

Thanks a lot !

 

Same problem of my car. The mechanic suggest me to replace the CCM. Do you fix the problem now?

 

Also, my mechanic told me his computer showing that the AC temperature ranged from -40 to 150 F. so he got the conclusion must change CCM.
