Air conditioner not working

Sounds like a good idea to test the high and low switch now here is the issue with that there is only one switch that I can see on my system it is on the high side inches from the condensor and it has 3 wires and is also not shown in the haynes repair manual wiring diagrams

Were you able to figure out what was causing your ac problem? Mine had too much Freon in it.

Found out that the problem was the control panel inside the car replaced it with a new one problem went away. Dealer item btw 130.00 bucks too it sure beat the items the repair shop told me I needed they said it was junk in my system from a failing compressor so I would need the compressor, expansion valve, dryer receiver, and a system flush 650 is what he said I like the 130 better hope this helps you

Oh great thank you so much! I will call the dealer on Monday!

Thanks to blanket00. AC was on sometimes, then blew hot air. I bought a used control panel on EBay and now the AC works great!

Hi,

I just bought a used Sebring, and soon discovered that the A/C only blows cold some of the time. On some trips it runs cold, then when I stop the car and get back in (like when I am running errands), it blows hot. It is always one or the other, never both on the same trip. Dealer did EVAC recharge and changed a switch (I don't know which one), neither of which solved the problem. I am going to take it back in, but would like some direction first. I live in the dessert, and it is awful w/out A/C. Thanks for any help you can give!

The ac gets cold as long as the car is sitting still but as soon as u give it gas the ac blows hot air also the comp will stop and then start when you rev the motor up also it the car is sitting at idle it gets cold but as soon as you take off it gets hot then if you stop it will start to cool til you take off again. I have drained the freon out and refilled it and still does the same thing need help.

Air Conditioning problem
2002 Chrysler Sebring Automatic 99000 miles

My air conditioner blows cool for only a few seconds and then blows warm air for a minute or so then repeats the same cycle. When it blows cold it is very cold, but it doesnà  à   à   t last. Any suggestions? Also, I was told something about going out on high pressure and I am clueless to what that means. I can't say I trust the source. Just curious if anyone has had a similar problem and how it was solved.

Six cylinder front wheel drive automatic 104,000 miles.

I have the Limited Convertible model. Recently I noticed the A/C was not providing any cold air.

I went to my local auto parts store and picked up an air conditioning recharge kit, which has the bottle of refrigerant and a gauge. When I hooked it up and followed the instructions, I found that the needle on the gauge was in the "danger" area really high pressure on the low pressure side of the A/C system. So obviously it was not lacking the refrigerant.

I suspect that maybe the clutch on the compressor is not engaging. I am not sure how to troubleshoot this though.

I did check the relays and they are all fine.

What would be the next step? I want to first figure out whether it is the actual air conditioning system or an electrical problem that is causing it not to kick on.

Yes. I do. I just do not have the wiring diagram so I have no idea where what goes where.

I did some additional investigating today. I found the wire that connects to the compressor clutch and I assume that this is supposed to activate it. When I connect a DMM to it and read the voltage from the wire to the ground, it shows zero. When I turn on the air conditioning, it also shows zero. I would assume it is supposed to be +12 when the AC is on. So I may be narrowing the problem.

I do not want to do anything without knowing that it is not going to cause damage, but I was thinking that perhaps I could figure out if the compressor and clutch are okay by just hooking up a test lead to the plug on the compressor and connecting it directly to +12 volts (with a fuse just in case) and if it causes the compressor to engage and the AC system to kick on, then I will know the problem is not with the compressor.

Is this a good/safe idea?

Alright. I connected the A/C clutch control to +12 and it seems to have engaged the compressor. The compressor seemed to kick on, and the pressure on the low pressure side of the system went down, although it still stayed pretty damn high. It went from about 110 psi to 80 psi, which is still in the red area of the gauge I have. (Which I admit is not the best piece of equipment, it came with a recharge kit)

Also, I feel no cold air coming out of the vents.

So now I am starting to think maybe there is a blockage? Unless there is a valve or something that is not opening.

Is it possible that the reason the compressor will not engage is that the pressure sensor is sensing that something is blocked or something and that is not allowing it to come on?

Someone told me I should try letting most the refrigerant out of the system and then re-charging it. That does not really seem like such a great idea, but I am not sure. Anyway, it is not the ozone depleting type, so I guess I do not have to feel bad about that if I do.

My Air Condition randomly shut off especially on trips over 45min. Some time just shutting off the engine is enough to get the air condition to work other times it need to cool off. Recently had it service and now it works even worst the air comes out randomly cold to cool and some times even a little warm and I am still having the random shut off issues. Before the service the air always came out freezing when it was working. Mechanic said he check system and put a 1lb and a 1/2 or coolant.
When it shut off the interior air condition light will begin to blink. Any suggestion would be appreciated.
Thanks
