Pull the belt? What would that do exactly?

If the problem is the compressor siezing up, the problem will go away when he removes the belt because the compressor will not put any strain on the engine.

Dont run the engine for too long like this or it will overheat. This should be a quick test.

Call it a car all you want. Some thin skinned people just like to get their panties in a wad because they can't accept the fact that their Jeep is a "car" just like some bike riders can't accept the fact that a Harley is a "motorcycle".

I really doubt it's electrical. The only electrical aspect of this is when the switch activates the clutch which makes the compressor spin. Check the compressor and its bracket.

Keep in mind that free advice can frequently be worth less than you pay for it.

What about if he rides really fat girls around when the A/C is cut on? Violent shake.

$20 bucks on the compressor, who ever you asked in your town, don't ever ask them for auto advice again.

I require things to do.

haha you wish! My friend was quoted $1200 for the AC on his van. They said that compressors don't usually freeze up unless there is a blockage in the system. then you need all the ac crap redone. There are 2 basic things that i would expect to cause this.
1. A compressor that is on its way out and "freezing" up a little to put excessive load on the engine. If you pull the belt off and run it for a few seconds you will know if that is the cause.
2. A bad or dirty IAC valve. If its old or sticky, or full of crap it won't work properly to add more air to compensate for the higher load with the ac on.

A long shot would be that you have bad 02 sensors, or a vacuum leak causing the AFR to be outside of the normal range and not run as well. But then it wouldn't run perfect with the ac off.

Why would it overheat? Our 2.4 water pumps are timing belt driven thank you very much

You can pull the belt and drive around til the battery dies.
