Question about 2000 Jeep Grand Cherokee
My air-conditioner stopped blowing cold. I recharged it with R134. It worked great for one day, then quit blowing cold again. Could it be the low-pressure cycling switch?
If compressor isn't kicking in, check the connector atop the a/c accumulator, beside the coolant recover tank, in the engine compartment. That connector is atop a black bottle, and the connector goes to the low pressure switch. These switches do fail, and you can jump a wire across the connector terminals to see if the compressor comes on (engine running). As this circuit provides part of the ground path from the compressor clutch, if the switch is open, the compressor will never turn on. If the switch is failed, it can be replaced without opening the a/c system. Just disconnect the connector, unscrew the switch, replace it, and reconnect the connector.

My 99 jeep cherokee is doing something similar, it will stop cooling, it seems like the compressor is still running but perhaps its not, when it stops cooling the low pressure side jumps up to 100 plus psi. i was advised it may be a vacuum problem. please advise
