AC Question

My ac clutch is kicking off and wont come back on unless you turn the ac off and wait a few minutes. I replaced the low pressure cycling switch and had the same result. I have a gauge that shows that I have plenty of freon. When the truck is just ideling it stays on just fine. Soon as you start driving a few minutes later it goes off. WHATS MY NEXT MOVE.( I am trying to fix it if it is something I can do) High pressure? Clutch problem? Faulty reading on my gauge? Let me know.

I agree with "fourhatz." Sounds like your low on refrigerant. When you drive the low side pressure will drop due to the air blowing thru the condensor and increased compressor speed. The compressor clutch is probably fine and is just doing what the sensors tell it to do.
