2005 Ford Crown vic air conditioner blows hot, compressor good, freon full, fuse and relay good. What could it be. Did it last week, I tapped on the relays under the hood, and it worked for a week, now will not work at all
Manal temp control, I got a new LCM last year this would not have anything to do with it would it?

hi, if the a/c blows hot have you check the compressor if it engages when you set the controls to full blast a/c function?
Customer: replied 6 years ago.
Sorry, I should have mentioned the compressor is not getting any power, There is power at the Fuse/Relay box, and then none getting to the compressor

ok, do you know what the pressure is on the low side and on the hi side? you may have a pressure or a cycle switch bad, but they may also be affected by pressure, can you have the pressure check.
Customer: replied 6 years ago.
Pressure was checked said it was good on both sides, even recharged it
