Hi Guys n Galls

 

Going through the diagnosis and testing section on the Climate control system via TIS and need to find the various components to fault find A/C problem - A/C light comes on but no apparent A/C. Read various posts on this forum but cant find anyone describing the location of the below:

 

1. A/C compressor clutch module

2. 3 way pressure switch

3. ATC module

4. Themo switch

5. PCM

 

I am a Galaxy noob please excuse my thickness :blink:

Hi there and welcome to the site

You dont say whether you have had the system checked and if no problems regassed by a specialist auto air-con engineer.

They will vacuum the whole system check for any leaks before refilling with gas and then adding fleurecent dye which can help find any future leaks.

Air-con will not work if the gas has leaked away.

Look under "412 03A - Air Conditioning" instead, then reference the "Removal and Installation" section for the clutch and cutoff switch. ATC module usually refers to the "Automatic Temperature Control" module which is the climate / AC panel itself. The thermo switch will probably be the iceover switch and thats located on the evaporator housing behind the dash. The PCM is the "Powertrain Control Module" or ECU.

Thanks guys for the info. Havent had the system checked by AC eng thought I might save a few pennies if I could check a few things myself first. Plus give me an excuse to familiarize my self with the vehicle.
