You may not have enough or any gas left in the system to allow the compressor to kick in , check the gas quantity first !

Hello,

 

How can I check the gas without going to a specialist?

 

 

thanks,

Same problem here - I have the manual a/c.

The button lights up, the fans run but the compressor pulley middle does not turn.

I can turn it by hand easily and it feels smooth with maybe a little resistance.

I have had a qwikfit regas, and that was ok but ineffective.

So, Where is the pressure switch, and which wires do what?

 

Cheers

iVE HAD IT CHECKED GAS OK ANY MORE HELP WITH THE PROBLEM?.IS IT 12V AND CAN I POWER IT UP SOMEWAY TO SEE IF IT COULD BE A RELAY PROBLEM.

You can apply 12 volts directly to the compressor to check it kicks in. Be warned however, if the gas has been overfilled as sometimes happens, you may damage the compressor. That is the reason for the 3 way pressure switch, which is in line with the supply to the compressor.

Seeif you are getting 12V to the compressor when it is meant to be running, it only has a two wire connection. If you have 12V, the clutch has failed and it will probably be cheaper to get a re-manufactured compressor than a new clutch fitted. This happened to me.

THANKS FOR THE QUICK RESPONCE i HAVE 12V AT THE PLUG THAT FITS ON THE COMPRESSOR,SO IT LOOKS LIKE MORE EXPENCE. Edited August 2, 2008 by mos

Hi

Please let me add my AIRCON expereince! The AIRCON failed in the winter and like so many we did not notice. Come spring and out impending holiday to the south of France meant time to sought AIR-CON. In the 3 yrs we have owned this car we have never had the AIR-CON checked. A mobile AIR-CON man arrived and there was about 650g - R134a gas in the system, Given the capcity was we thought to be 750g the system was serviced. The temp at the vents was 5--6C with OAT of 19C. I was happy with that as the AIR-CON had never been great. Overnight, however the GAL had lost its AIR-CON; at this point I thought this is serious money.

 

Off I went to a really freienldy knowlwdgeable chap in South Lincolnshire, whose address was found on E-bay.

 

First problem not enough gas according to AIR-CON chap my GAL should have 1050g of R134a, I was very sceptical as TIS says it should be 750g! Anyway in went 1050g and I waited for the 3 way pressure switch to kick in, everything fine for 10 mins then the HVAC module went haywire, the pump compressor kicked in and out on its own accord. Again this looks like serious money.

 

The status so far then is System = no leaks; pump OK when running; no faults on VAG-COM. However the AIR-CON would start and operate for 10 mins, then a pulsing of the engine could be sensed, this was traced to the pump clutch going in and out of engaugement.

 

OK time to learn how this system works, our is system without ATC (auto temp control). There are a number of sensors that have the ability to switch of the AR-CON, the three way presuure-switch tested fine. Gooing deeper located in the LH wing adjacent to the water bottle is the AIR-CON OAT temp switch. This switch operates at 5C an shuts dwon the AIR-CON if the OAT is below 5C. I tested the switch off the car and it failed intermititlay with air-con ON. A new switch from FORD and everything is no Ok we have 2-4C at the vents which is superb.

 

Our GAL 1.9tdi zetec 59k miles model 03
