Ok so I had the ac working for a bit. But then it went off again. I tried jumping the low pressure switch and the clutch would not engage. What could the problem be? It seems as if it is before the the lps. I dont know im lost any help would be greatly appreciated

Check The WOT relay. It shuts off the power to the A/C clutch at Wide Open Throttle (hence the name WOT relay). Th wiring for the relay socket tendsto get overheated and deteriorated. The Wot relay is located on the passenge side strut tower below the MAF.
