Yj wrangler ac

I've been having a bit of a problem with my ac in my yj wrangler it blows cold when it wants to and then at times it will stop blowing cold air and blow hot air. Only way I can get it back to cold it to turn it off for a bit then keep turning it on and pray it comes out cold but by then I'm already drenched in sweat. Is there something I can do to fix this? I believe it has antifreeze? Is it because its so old? Do I need to change the compressor? Maybe a hose or something is broken? What can I do

If it works at all, it means it has freon and the compressor works. Perhaps the compressor clutch is failing and intermittently doesn't engage when commanded?

how long has it been (if ever) that you had a basic recharge of the system? or a complete evacuation and refil? could be due for one or the other.

It can also be high or low freon.

Since I've had the car which has been for about 2 years I've never done that. Can any regular mechanic do that or is that something special?

You can do it yourself.

Hope you don't mind that I moved your thread here.

Keep an eye on the ac clutch. It's in the front of the compressor. Could be it's going bad.

My guess would be the compressor clutch is going bad, but as stated above being to low or to high on refrigerant will cause the system to not function proper. One thing you could try is when the ac is not working correctly unplug the wire connector that is on top of your receiver dryer and use a jumper wire and see if the clutch kicks in. If it doesn't then that will tell you your clutch is bad.

My 90 had a similar problem. I cleaned the contacts on the ac relay, and the plug on the compressor. It helped, they had a lot of corrosion built up. But now it intermittently happening again. But now if I turn it off then right back on it blows cold. I think my problem might be the power switch it the temp knob
