After having my condensor disconnected after a radiator replacment job, I had my vehicle's AC system vaccumed and recharged by a friend who works at one of the major local dealerships. My AC now only works when driving. If I am stopped it blows warm air NOT hot. As soon as I begin to drive or if I rev the engine above 1000 RPM while stopped it will blow Ice cold air. I have checked the compressor and it is engaging while stopped but yet no cold air?? Cooling fan is also running normally while stopped. Really confused.
Hello
Based on what you have said and my 30 years a Ford dealer tech I believe you have a slightly low AC system refrigerant charge due to a small leak at the AC compressor or the AC line connections. I would have a shop hook up a set of gauges to monitor the pressures at idle and see just how low it is. DO NOT ADD UNTIL YOU KNOW HOW MUCH IS NEEDED, YOU CAN LOCK UP THE COMPRESSOR.

I would check the level of your coolant first and foremost. A lot of times failing to prime the coolant after a large procedure like you just had will be the cause. Also, Ford (lincoln) is notorious for their vacuum powered systems failing which is what controls the baffle on your cooling system to allow the hot coolant from the engine to heat the air in your heating system. Hope this helps

I've seen no mention of the 10 Amp fuse under the hood. Has anybody checked to see if that is blown? Mine has blown 3 times in the last 2 months.
SOURCE: 2002 Lincoln LS V6. AC blowing hot air but
its probably the compressor cutoff switch cutting your compressor off at the wrong time and causing your ac to blow hot. that switch is under your hood right on top of the engine easy to get to. I hope that helps you out!

Needs to be recharged and you more than likely have a leak somewhere
SOURCE: heat blows out driver vent when ac on
this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.
