2006 fordf350 6.0 have an air conditioning problem. Runs good when idling goes in and out when driving down road.

 

If you use the search you will see that I asked this on Sunday (4 days ago) and nobody responded.

Through my own research I found that the likely suspect is a faulty high pressure switch that is located on the compressor.

Mine must have been a circuit breaker that reset itself, Sunday, grounded battery (oops) no ac above idle, Monday going home from work, normal ac.

 

We just had the same problem we had to cange the hole compressor the. cluth was going bad when we would put it under pressure the cluth would disengage

 

I would put a set of gauges on it and check the pressures we have a ton of problems out of the low pressure switches on the trucks we have at shop.
