Hello techs,
am working on a Mercedes ml w164 Air-conditioning, its not getting cold and I have error P9006, I have changed A/C compressor but still the same,where can I look? or a wiring diagram may help.

thanks in advance.

I just found out that there is no auxiliary battery in the car, can this cause the non functioning A/C?

Aux battery has nothing to do with a/c function. have you tried to actuate the compressor or have you performed compressor break in with SDS? What is the description of the code that your are getting? Is the code in AAC module, front sam?

[spanaz1]

No. its short circuit to A/C compessor

if you have replaced ac compressor

check pin ( acc pushbutton control module) B. 26 to groundd ( 5-20 ohm)

and wrire from( acc pushbutton control module) to ac compressor > 3 ohm
replace acc module as picture
then adapt ac compressur

i have faced it
