Hello! finished work early so decided to have a look at my mums car! She has a 51 plate golf TDI the air con compressor isn't kicking in with the AC button even though it is lighting up (non climatronic control). I did a scan with vag-com to see if anything came up but it shpwed nothing. I have checked the voltage to the compressor it is 8.89v both turned on and turned off in the cab. I checked all the fuses in the box next to the steering column, does anyone know where to loook next?
