Air Con Problem

[v6power]

Hi All,

 

A problem with the air con. Firstly, how do I determine wether I have rear air conditioning?? I have vents under the 2nd row of seats, but none in the roof.

 

I had it re-gassed yesterday, but it is still not cold. The technician said it could either be the pump or the control unit. With the engine running, you can see the pump spinning, but none of the pipes are cold. He therefore suggests that the pump is at fault, but I would like to be as sure as possible before throwing that sort of money at it.

 

btw it is an 04 TDi 130 Ghia

 

Thanks in anticipation

Ade

If you have no roof vents then you don't have dual air conditioning.

 

Can you hear the compressor clutch engage (a fairly loud click) when you switch the a/c on?

you havnt had it refilled with to much refrigerant have you,there are a few posts on the subject where if you have to much in the system it will not work properly and if fact may/will damage the system.

We have overfilled it!! Although that isnt the reason for not working as we tried the smaller amount first. I cant hear any "click" although the pulley is spinning freely??

Could just be a faulty electro clutch. MEasure the resistance across the terminals on the compressor, you should have about 3.8ohms. If not then you can just replace the clutch which is a darn sight cheaper than a new compressor.....

A chap at work had a pump that he had taken off his Corrado. Same part number, fitted & working. Cool as!!! Edited July 13, 2010 by v6power
