Title: air con problems need help!
Post by: Andy1994 on November 02, 2013, 08:34:57 pm

Scanned car with vagcom no codes!, scanned car with launcg diagnostic and had a code for "refrigerant pressure low". Checked the system which was full and no leaks so replaced the pressure sensor rechecked and no codes however i still dont get cold air and the fans dont come on but, when i press the econ button to either turn on or off the revs do fluctuate at idle as if its working so can shed some light on what my problem is

Use VCDS to run an output test, then use measuring blocks to run the fans & check compressor current see what you find.
