You can turn on a/c and at idle speed the temp. will hold around 40 degrees, low side psi 30 at 100 degrees outside air. suction lines are sweating great. Will continue this way until you start driving the vehicle or otherwise raise RPMs then the compressor disengages and will not come back on until vehicle is turned off, then the whole process starts again. Any thoughts on this one? Thanks it's hot out here!

Have you monitored the power feed to the compressor to see if it's losing power or the clutch is just losing strength. It could also be temp related. Fords will shut off the A/C when they get hot or if the TPS is shorting to power, the relay will cut out. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. nickwarner Veteran / Moderator Jul 3, 2012, 6:30 PM Post #3 of 3 (2379 views) Re: Ford ranger a/c compressor Sign In You only mention low side pressure, which makes me think you're using the gauge that came with a bottle of 134a. What has been done to this truck previously? Did you add any refrigerant to this and if so was it pure or the stuff with leak sealer in it (referred to by techs as the Death Kit)?   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
