2000 Jeep Cherokee Air Conditioner

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?

    My A/C stopped blowing cold, started blowing barely cool and one side of the Jeep's vents (passenger side) is now barely blowing (hot air). I got the A/C recharged and it lasted a few days. Now I'm back in the same situation.

    Same with me. A/C quit blowing cold. Now only hot air. I can tell the compressor isn't kicking in. Any ideas?

    Yes, the compressor will blow for a short amount of time, then blow
    warm air. We had thought it may be the climate control switch, but if
    it is blowing some air then, then it may something els? I will
    check the switch issue to see if it is that.. Greg

    My compressor is cycling on and off but the recharge only lasts about 3 days. Is there an easy way to find the leak?

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

My 1986 300e air conditioner works great, then cuts off. I start he car and it works great and ice cold. Then goes warm. Is it freon?

First your ac comp has a clutch. second r 12 and r134 are NOT compatible if you just "add a pound of r134" you will kill your entire ac system. The O rings, dryer and pressure switches are not interchangeable nether are the lubricants and you WILL burn up your ac comp. Just a word or caution. It is probably the ac speed sensor to detect slip.

It sounds like your blend door isn’t operating correctly . The blend door simply is a flap that is designed to close off heater core when it’s calling for A/C , and opposite for heat . Check to see if it’s operating
