Why would your ac compressor lock up when the switch is turned on in your 1997 ford ranger?

The air conditioner compressor is made of several parts that need to move to circulate the refrigerant through the system. There is the pully, shaft, bearings and lifters or pistons inside of the compressor, the compressor motor has a clutch. When the belt on the engine turns it turns the shaft on the compressor which is held in place by bearings, the shaft moves the lifters to circulate the refrigerant - the most likely cause for a compressor to lock up is missing or misaligned bearings. Other possible causes, belt loose or not on properly, shaft bent, compressor motor not working correctly or clutch worn, pully stuck. Generally you would have to replace the ac because of how the serpentine belt is threaded onto the engine. Check to see if you can bypass the pully by getting a smaller belt, but it is important that the belt be threaded right for all the other engine parts to move correctly. The ac compressor usually runs about 2 - 4 hundred dollars new. You can also get rebuilt ones or go to a reputable junk yard for a replacement one.

Why wouldn't the AC compressor turn?
The most likely reason the compressor is not coming on is because you are low on freon. The low pressure switch will keep the compressor from cycling on because damage to your compressor would result. You can jumper across the low presure switch with the engine running and A/C turned on, ( for short time only) this will provide you with question is my compressor clutch good, or am I just low on freon. The AC compressor relay switch may need to be replaced

Maybe the compressor clutch is not being sent power from the switch in the cab. I'd yank the panel out and have a look at the switch. FriPilot

Is there a fuse under the hood for the AC compressor on a 1999 Mercury Villager that would cause the compressor not to start when the AC is turned on?
Besides fuses,there are relays that activate this compresorm most of them located under the hood; however, most of the compresors have a pressure control switch, if you have a small loss of refrigerant, eventually it is going to loose pressure an your compressor will not start to prevent compressor damage. Evacuate the system and refill with the correct amont of refrigerant.
Why would your car make a rattling noise when the air conditioner is turned on?

Why would a '92 Buick Regal 134a compressor fail to engage except when jumped directly after attempting to convert?
On the dryer, there is a cycling switch which also cuts off the compressor when the preasure is low. Perhaps the switch is defective. GoodluckJoe

Where is the fuel pump shut-off switch at?
Most users of the fuel pump shut-off switch is near the starter button in a location where a thief would not find it. You can hear when the fuel pump switch is turned on and of course when turned off there would be no noise.
