Air conditioner comes on for 5 minutes then shuts off for 10 min

I have a 2000 Limited and I have had the AC system Charged.. The thing is it only lasts for 5 minutes... then it takes 10 minutes to thaw out the ( condensor ) Im guessing.... What could be doing this? Expansion Valve or low-pressure cycling switch? I bought a Hayes Manual and it said it had no detailed info and to buy the air conditioning book by Hayes... WTF? LOL,

    Hi! My father In Law has an Auto Repair Shop with all the AC equipment. were just trying to troubleshoot now.. Since we dont have a clear diagram of the 2000 Jeep Cherokee Limited A/C system.. Do you have any suggestions where I can buy a real manual? Your right the Hayes is useless!

    I've never seen it, but if their a/c book is anything like their wiring diagrams, it's worthless. unless you have a good set of gauges and an evacuation pump (+ lots of experience) You are better off having a good shop fix you up. I'm all for people doing their own work,(or I would not be here) but this is one area that it just is not worth it.

I have a 2000 Dodge Ram 1500 that will blow cold and hot air for only a few minutes. After that is only ambient air temps. It is a 5.7 ltr, automatic with only one set of climate controls. The heater core...


you say it will blow cold and hot air for only a few minutes. You don't say but I assume you mean will blow cold a few min. when turned on AC max , blow hot only a few min. when turned to heater hot. Assuming thats the situation and you say AC charged and shows good on the low side -you should charge the AC to a full charge on the low side will cause problems with the AC air compressor kicking on and off. I suggest while the engine is running and turned to AC cold max watch the AC air compressor clutch to see if it does indeed kick on and off if so charge completely. As far as the heater make certain you coolant is all the way to the top and the best way to do this is when engine is completely cold remove radiator cap and fill completely and completely close cap then fill overflow container just to the cold level. That should fix your problem.

I have a 2003 Jeep Grand Cherokee Limited with 4.7L, recently its been hot out and have runing my AC, it will run for about 10 mins then it would shut down, What you think it could be?


Are you saying your compressor is shutting down? Or your vehicle? If it is the AC pump I would get the unit charged because it sounds like it is low on freon.

If you are saying the vehicle shuts down, then we would need to know what all is affected before we could give you a WAG on that one.

A/C on my 2000 s70 blows cold when working then just cuts off. If I turn A/C off and back on in about 10 min it works again for a limited amount of time


Possibly expension valve , if a/c comes on only for couple of minuts and then shuts off , and then works the same way after 10 min.

My air went out...


My 2001 limited did the same thing. I bought a refridgerant refill kit from Walmart and plugged it in, but it showed that the level of refridgerant was fine. Turns out the AC belt had come off. I found it laying in the skid plate. My auto shop charged me $25 for a new belt and putting it on.

The air conditioner switches off


If you are positive it is full, then I would have someone check the pressure switch on the evaporator. When the system pressure drops, it will shut off the system. Usually people think the system does not work when I buy a car, and 9 out of 10 times it is just not fully charged. I wish you luck and have a great day.

Air conditioner won't stay on.


'64 could be right, but these Malibu's also have a tendency to go through HVAC head control units, among other things. I have taken the head unit out of mine and cleaned the contacts, etc...with some success. However, from what I've seen, this is just a temporary fix. These units run upwards of $200 at a dealer, but you can get one online for just over $100. It is a really easy install.

Other common problems include:
-Cruise control modules going bad (cruise kicks off at will)
-Bad resistor on fan blower (only speeds 3-5 will work)
-Front coil springs breaking
-Front brakes wear funny, excessive wear
-Moisture in headlight housings
