Might be a fuse. Be sure and check your fuse box 9 times out of times its something in there.
a/c not working
so last dec i had to replace the heater core in my 03 liberty. while i was in there i noticed the a/c evap was nasty, it had green mold, fur, and and more on it. so i also replaced that since i was in there. but the a/c now does not work . i filled and charged it. at first, it would only NOT work while in idle, (say at a stop light, or parked), but now it wont work at all. i have checked all my levels. the thermostat is fairly new, the a/c compressor is fairly new (it works , it turns like it is supposed to). the coolant levels are normal. so i dont know what i have missed. can any one please please help me. my windows dont roll down so i NEED a/c. lol . (im working on getting the window to work)

yes the cooling fan is working the ac compressor is working. i did check the lines like another person said. about one being hot and the other being cold. well on was cold it had condensation on it. and the other was hot. and it was hot near the radiator

i checked it and yes . and the one that is cold has condensation on it. and both lines are hot the closer they get to the little box that is connected to the radiator
I will suggest then that what you have is a blend door problem. Unfortunately I don't know all the ins and outs of those issues on your model

I guess they test the compressor down at your Pep Boys
I would suggest a set of gauges next. Post the pressures on and off on both high and low sides.
Since the compressor runs and the return line has condensation on it, that part of the system is working. Back in the day we used "a good sweat" to know when it was close to being perfectly charged. I will say again that it is under the dash that the problem exists
You could be right, they are known to have blend door issues.
I won't guarantee that it is charged completely right since I can't verify air flow across the coil, but I can be very confident that it is a blend door issue
