A/C system question
I have a 2000 f350, my a/c wont stay cold all the time. It cycles from cold to warm while driving down the road. What would cause this? What should high and low side pressure be?

Forget about the pressures, at least for now. They are probably not part of your problem.
These are classic symptoms of a too-large clutch air gap.
This has worked for a lot of folks:

Do as Pop mentioned...check the air gap on the clutch. Also you might want to consider valving the hot water line to the heater core. Here is a thread on it...

Havent had a chance to check comp clutch out. But I bought a new set of snap on ac gauges and decided to test them on my truck. High side was 280 psi and low side was 40 psi on high idle 1200 rpm on max ac and blower on high. Do the pressures sound right
