AC is F-ing up. Help Please
99 F250 Super Duty 7.3
Recently charged my AC and it works fine UNTIL- I get going down the highway (60 mph) then it starts blowing warm air. When I turned off the highway the compressor kicked on again and worked for a little bit, then quit again. When I parked it here at home I opened the hood to see the compressor was not working at all. Later, I went out to see if would work. Turned on the AC, and it took a few seconds for the compressor to kick on, then it stayed on like it should, then after it had been running for a while it kicked off for a few seconds every so often, which I think is normal, right? So what can it be? Relay? Compressor? Clutch? Help please!
