Air con problems...

[Gmac]

Afternoon all!

Need a wee bit of help with my non-working aircon...

Problem...It's not blowing cold.

What i've done so far...

Checked fuses...there seems to be reference to two 40amp fuses in position 22 and 40, but not sure if the position 40 one is needed?  So could someone confirm if they have two 40amp fuses in position 22 and 40.  I only have a 40amp fuse in position 22, and there is no fuse at all in 40?  The 40 amp in position 22 is fine.

I've checked the small fan on the left (when looking at the front of the car) and with the car off, it spins freely, as does the big one.  With the car running at idle and the climate control temp set to low on both sides of the dual zone, neither fan is spinning, which I'm sure isn't correct?

I've also scanned for fault codes using my VCDS, and its throws up this code...




So any other pointers, perhaps more diagnosis using VCDS measuring blocks?

Thanks

Might sound like a silly question, but is there gas in the system?

Since the aircon isn't working both fans won't spin up at idle checks.

Reading from VCDS implies what the previous poster stated. Reason for no gas is normally pressure switch has gone porous though the electrical connection point or the condenser is leaking someway.

My next move would be a regas with dye added for leak detection and recheck with VCDS - just find the best price for the regas cause the switch takes up to a week or two to leak away a full charge.

Not a silly question....and the answer is, I don't know. I've just bought the car and the previous owner's son was selling the car for his parents and he didn't know when it had last been working/regassed.

I'll try and get along to a local Kwikfit, who will test and regas.  If that doesn't work then they don't charge you.
