[GT11]

I Jump the pressure switch. Start the truck and put the fan on high and ac switch on max cold. Compressor will not run. I bump the clutch on the compressor with a flash light and it engages and starts to cool (touch cold on the accumulator). I then turn off the ac in the cab. The compressor stops, as expected. I wait about a minute and turn the ac controls on again and the same thing happens. Compressor will not run unless I bump the clucth assembly on the compressor. Whats going on?

Thanks
