What could be causing my Ford Explorer AC not to turn on?

Answer by  Allstar (2071)

It could be a blown fuse or burnt out relay. Check those. It could also be running low on refrigerant. You're best off taking the car to a professional to have the AC serviced.

The AC not turning on could be caused by a blown fuse. It could also be caused by a fusible link. The climate control panel could need replacing. The compressor or AC motor could be faulty. There could be a shortage in the wiring. The bearings in the fan motor could be malfunctioning.

You could have a broken AC and should probably take it into a dealership or at least a autoshop. It might just be simply overheated. or maybe the motor broke.

First check the fuse. Next check to make sure AC belt is present. If the compressor is not coming on have the system checked for an insufficient amount of refrigerant.

Answer by  Allstar (2071)

What I would check first is less likely but easier to fix yourself: the fuse and the relay. If they're blown/broken, replace. More likely is a loss of refrigerant, which happens over time. Low refrigerant causes the system to stop turning on to avoid damage. I don't suggest you recharge it yourself, take it to an experienced mechanic.

the AC system pressure can be low, the compressor could be bad, it could be a blown fuse, high pressure switch could be bad, belt might be slipping

there might be a leak in your AC system witch would make it not turn on at all if it is low enough
