I have been having a few issues with my aircon. It is now gased and I can dab 12v on the coil lead and it works. This is good. But does not work from the aircon switch in the cab.
All fuses and relays seem good, so that leaves 1 of 3 things. But I do not know where to look for them. Can anyone let me know where the 'Trinary Switch', and 'Thermostat' is. The only other area is the aircon selector on the dash.
Has anyone had probs with this ? How do I get to the back of it ?
Please call or post this thread if you have any ideas.

The ac control switch is accessed by removing the front louvered panel under the car. Here is some info supplied in the US Assembly Manual regarding the ac system and the control switch operation. The actuating lever has been known to come off. Hope that helps.

I do have heater/cool air in the car and all the speed selections work. But when I press the air con button, the light comes on but does not energise the compressor clutch. The clutch is fine as is the last relay to it in the engine bay. My problem is electrical. One of the three series switches to the final energising relay is at fault and I can't find them on the car to test them.

Cripes, that makes our UK owner's manual look like a Noddy book!

Why didn't Noble send me this info when I asked for it.
Right, I think my problem is with the thermostat. All I have to do is find it. Any ideas ?
