Just happened turn it to ac and nothing happens just blows hot air ac if full of freon any help would be great it is hot out
My lincoln had the same issue, first it was the A/C compressor (original). I replaced it with another one (used) and worked for 1 month. Then back to hot air. "A/C experts" told me the compressor was out again. I took it to a Mexican auto shop, old building where the guy works alone and to my surprise...HE FOUND THE PROBLEM!! There was no freon leaks, the lines were freezing cold inside the motor, checked freon>>full. He then checked the filter. This filter is on the end of the line where it is crimped that allows the freon to flow thru. Im no mechanic so explaining what it is, forgive me. I can only show you...the line is silver ad in front of you by the radiator, and its the same tube that goes to where you plug it to add freon. There is a filter that was clogged up and prevented the freon from flowing. He removed all the freon, vacuumed out the system/line, and replaced the filter for less that $3.00. Added freon and his cost was $80.00. Thank God for honest people who work hard for a living. I buy the parts, he replaces and I continue to give him my business. Other expensive auto shops with fancy buildings/prices My Lincoln Mark LT now blows arctic cold air!!!
I assume you know it is full of freon because the compressor runs ?
Is one ac line cold and the other hot in the engine compartment ?

You also could have air in your coolant system. You can't just add coolant on these models after you drain the system or let it run low on coolant. The degas bottles on these models also have a flaw, where they crack along a seam. Sometimes coolant will leak, sometimes not, depending on how high the crack is on the bottle. But what it is guaranteed to do is allow air into your system, which can cause havoc with overheating (air surrounds the thermostat so it doesn't open) and keep coolant from flowing, particularly through the highest point in the system: the heater core. There is a heater core bleeder valve attached to a line near the top of the degas bottle (next to the expension line up top) with a plastic, flathead srewdriver face. Turn the heat on high and run the system at idle for 5 minutes. Then open the valve and keep it open until a steady stream of coolant comes out. (It's like bleeding your brakes.) That will clear any air from the system and at least give you peace of mind that this is not your problem. Then run the motor at 2000 rpms, with the heat still on high, for about 5 minutes or until hot air starts coming out. Release the bleeder valve again until a steady stream comes out. Then let the system cool and check your coolant level and fill as needed. I'd pull the degas bottle and inspect it...should have been a recall.
SOURCE: The a/c in my 2001 lincoln ls isn't blowing out cold air.
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.

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.
