WOT a/c switch

VeNuM · 07-18-2002, 05:01 PM

My a/c clutch hasn't been engaging, so I traced the problem back to either the clutch itself or the WOT switch. I tested the pressure switch and it appears to be ok. Problem is, I can't locate the WOT a/c clutch switch, anybody know where it is at?

The switch for the WOT on your A/C should be under your stock air box on the fender well. I had a bad switch and just cut it off, spliced the wires together and it fixed the problem. There will be 2 different switch relays there, so just make sure you get the right one.

How's the freon? Have you checked it? If it's low, the clutch won't engage either! Good luck!

I didn't think it was possible to charge the system without the compressor on. I thought that the compressor "sucks" the freon into the system, I know there is little or no freon, it's already been converted to r134a and I have a refill kit, should I try to recharge it and see if the compressor comes on?

The low freon is the reason the A/C clutch doesn't engage.

Follow the instruction that comes with the recharge kit, shortly after pressure is applied to the system, the a/c will start to 'cycle'. Hence, the a/c doesn't have to 'suck the freon into the system.
