Thread: air con

Hi Jake, There was some good discussion of air con circuitry on Aulro a couple of months ago - you might want to try a search for it. One thing I remember from it is to check the thermostat switch that is part of the temperature slide control on your heating/air con controls. There is a small switch on the back of the slide control behind the facia panel - it is apparently adjustable with a tiny screw on the switch housing and you should be able to hear it click when the slide control is operated just slightly away from the extreme cold (blue) end. The thermostat sensor tube ,which is poked into the evaporator with a pipe back to the switch, also can fail and therefore not operate the switch to clutch the compressor in and out when temperature rises and falls.

I've also read that if your compressor cuts out too readily, depriving the cabin of cold air, then partially withdrawing the thermostat metal tube from the evaporator makes it hang in longer before getting to the level of coldness that triggers the switch to cut out.

Hi arron.

Cheers for the reply ill check that out this morning. I did however bridge the two wires that come from this switch and still didnt seem to make it work
i also bridged the thermostat on the evaporator. ill check em out again and see how i go

Instead of bridging ... use a multi meter and double check with a test light and follow the line of 12v power, starting at the A/C fuse >>>> forward ....
