Air con not working ;-(

(1/5) > >>

Drapoon:
My air con seems to have packed up ;-(.

07 golf gti

It was never great when I first got the car but now I just get a warm breeze even on low setting. There is also a high pitch noise coming from the unit every now & then which stops when the car is stationary. I have noticed that my fan at the back of the radiator makes a racket at idle too - any ideas?

I hear condensor unit is a common fault?

scotta:
May be low on gas - get it in to a garage to test it.

The local garge i use has air con servicing kit that can pump dye gel in and preasurise it to see if there are any leaks. if not they then top it up. cost about £50

andrewparker:
Is the fan spinning when the air con is on?

Drapoon:
cheers for the advice fellas


The fan is spinning when the air con is on yes - but it sounds like a spitfire at idle which I never noticed before....

80% chance it's your pump gone bad.
read this link and use my pictures to identify you make of pump, if you got the bad make, source one on Ebay.de. by far the cheapest and the same pump as VW uses, AND it's not a refurbed one.
Also make sure the garage cleans the WHOLE system before fitting the new pump.
There is a TSB on this fault.  :happy2:
