How do I fix ac

The correct fix would be to vacuum everything out and weigh in the correct amount.

Replace the AC relay with a known good relay in case the relay points are stuck closed engaging the AC clutch full time .

Check ac relay. If its good get pressure checked. Lo pressure ((freon) will cause your compressor to not engage which means no cold air. Hopefully you don't have any leaks and a new relay or a charge will fix you up

Have you tired jumping the AC compressor low pressure switch?

The very 1st thing you do is see if the AC system has lost its charge of refrigerant. If the system is low on charge then the relay will not engage because it receives no signal from Compressor cycling switch which in most Fords is located in the low side AC line from the compressor, the low pressure line is the larger of the 2 lines from the AC compressor..

The low side pressure switch in the AC low pressure line signals the PCM (computer control) to close the AC compressor relay and raise the idle speed. If the system is low on refrigerant charge the relay will not allow the system to engage the compressor, this is because the oil that lubricates all the works is suspended in the AC refrigerant, if that is low then the system gets no lubrication and will quickly seize up..

Over charged ac or leak in line

WELL TURN ON AC MAX COLD HIGH TO SEE IF COOLANT FANS TURN ON.IF NOT YOUR REFRIGERANT SO LOW THAT THE AC REFRIGERANT PRESSURE SENSOR WONT CLOSE CIRCUIT TO TURN ON COOLING FANS.MEANING YOU NEED HAVE AC CHECKED AND CHARGED.ALSO CHECK COMPRESSOR FOR POWER IF NOT YOU HAVE BLOWED FUSE OR BAD RELAY.IF FUSE AND RELAY GOOD YOUR AC COMPRESSOR CLUTCH COIL OPEN OR THE AC CONTROL SWITCH IS BAD.IF COMPRESSOR IS RUNNING WHEN YOU TURN ON AC YOUR AIR TEMPERATURE ACTUATOR NOT WORKING.

fan clutch is not energizing, is it?
