A/C switch and Recirc switch not working...

[Derek A.]

I tried to fire up the a/c yesterday and the switch would light but would not turn on compressor. This morning I turn the car on and the light comes on and the compressor runs, blows cold. I turned it off and cannot get it to turn back on, also noticed that the recirc switch is not lighting up. Anyone have ideas ?

Thanks

I had the same problem, worked sometimes, not others - affected both air-con and re-circ switches.

Main dealer diagnosed it as the switch, but they couldn't be bothered to spend time looking properly and were wrong!

Took it to an air-con specialist and they checked over all the wiring and found a dodgy connection right down at the front of the engine compartment around the drivers-side wing (on my RHD car anyway - passenger-side on LHD) There was a connector down there in which the points had corroded badly. They chopped the connector out and hard wired it, worked perfectly afterwards.

Of course, might not be that - but your problem sounds very similar to the one I had.

I would assume that following the wiring from the compressor would lead me to that block as they are mounted on the RH side of the car.

Thanks for the input.

That's what they did - just followed the wiring round until they found the fault.

Good luck
