Yet another Air Con woe......

(1/5) > >>

Boothy:
Well after finally getting my simple but very awkward boost leak sorted my bloody air-cons just packed up! I can't f**king believe it :sad1:

I know there are lots of post in relation to compressors being duff etc but I was hoping somebody might just give me some advice diagnosing what might be the issue before the credit card comes out to play.

 Its been working fine however when they fixed the inter-cooler pipe (that was leaking oil too) they must have steamed or jet washed the back of the radiator and the bottom of the engine bay where the bumper goes underneath as its very clean indeed. That was on Monday and the air-con has been working fine all day Tuesday and first thing this morning however when I've started the car later this eve its just blowing warm, regardless of the setting.
 When I got home I checked that the fans at the front were working and they were both turning however when I turn the air-con on or off now they don't move. Also when its in Econ mode and I turn it off the revs don't drop at all and there's no noticeable change in noise etc. I don't know what that means but remember reading somewhere that it was important with regards to air-con.
 I've checked every fuse in both boxes and they are all okay.
 Just where they have steamed/jet washed there are too sensors. One connects directly onto the rear of what I believe is the compressor (located just below the alternator) and then one on the far-ish left that appears to be connected directly onto one of the metal air-con pipes? I'm wondering if some liquid might have got in there somehow and caused the issue? They are ridiculously hard to get to with my sausage finders so I've sprayed a bit of penetrating fluid on in the hope it will force any moisture out.

Somebody please tell me it sounds like something cheap (but don't lie)!

Boothy.

If theres no noticeable leaks  - regas the Air Con ??

Boothy:
 No noticeable leaks mate. Checked the system for pressure and it seems ok.

I had exactly the same issue with  a pug 206 GTI i had a few years back. I didn't get the 'click' when turning the system on etc.
I had only had the system regassed 2 months earlier. Dealer suggested some kind of air lock in the system.
Another re-gas and check for leaks with UV light & die in the system and all was well.

As long as it's not the dreaded compressor. Fingers crossed

Boothy:
The whole forum should cross there fingers for me mate as I really can't afford a new compressor.  It's booked in to the stealers on Tuesday so hopefully it'll be something simple.
 So come Tuesday, everyone please cross your fingers for me.
