Air Conditioning Clutch & Relay Number

[Audiman]

Hi, I've got a Galaxy MK2 1.9TDI. The air conditioning stopped working last week.

I've checked the air con. clutch, looks like its not engaging. I've also checked all the fuses in the fuse box and near the battery.

All fuses are good.

 

Does anyone know what relay to check (ie relay number and location - suspect its behind the fuse box.

 

Also I've read that the clutch may not engage because of low pressure in the system.

Most likely culprit is low pressure, the combined pressure switch will indeed stop the clutch pulling in.

 

If it's been intermittant, you may get away with a regas, but if it's gone altogether you may have a leak. Part of the regas procedure is a vacuum test for leaks, so it should fail at that point if you do have a leak... or small leaks can be identified with a marker dye in the gas.

 

The main source of leak problems on the mk.2 is on the condensor, there's a thread about it on here somewhere...
