Ford F-150 Clutch Problem
I am having an a/c issue in that, i was traveling last weekend and for no reason the a/c compressor kicked off and would not restart. Thinking it through, i was sure that i had a low freon situation that caused the low pressure switch to kick in and shut off the compressor. so i stopped and bought a can of a/c recharge from Oreily, one with the cheap hose and gauge, and began adding freon, after a couple seconds of attaching the can the compressor kicked on and ran. It ran for a bit pulling down the can of recharge until it was all but empty. at this point i think the problem is resolved, unhook the hose and as soon as i did the compressor shut off again and would not restart. New thought, ive overcharged the system so i purged so off but to no avail. Now that i am back home i got my gauges and i have 70lbs of static pressure in the system, enough to run or at least try in my opinion.
So at this moment i have checked the low pressure switch and have power in and out of the switch, took a jumper wire directly to the compressor and it will engage and run as normal so long as i hold the jumper wire in place. not sure how to test the high pressure switch. Did find the a/c clutch relay on the driver fender well and replaced it with a new part from Ford. All fuses are good and have been checked and triple checked. Im stumped and hoping that i can get some much needed help and avoid having to take it in to a shop.
