Have had a quick search and can't find anything that helps. My air con is playing up. Set at 21 today (26 degrees) and it went on full, then... Windscreen vent - ice cold Driver's vent (near headlight switch) - cool Central vent - Ambient Whatever setting I used (feet, top only, top and face etc) the temp stayed the same out of the vents. Then I set it to LO - no change. Then I set it back to 21... Lo and behold, the central/driver's vent then cooled down and became ice cold and it went on as normal. That's weird and I don't understand it. ECON light is not on, was re-gassed last August and no faults are showing in VCDS. Any ideas anyone?
