No power at all ?

Manual a/c or climate control ??

Has the A/C relay been tested, is the 10a HTR-IG fuse ok ?

Is the A/C relay being commanded on ??

Does it work if you feed it 12V, have you replaced the A/C amplifier ?

Does the outside temperature read correctly on the orange display ?

Has the pressure sensor been tested ?

Check the fuse

HTR-IG 10a

To diagnose the a/c amplifier, you need a scan tool or access to Techstream to look at the error codes
