Air conitioner clutch

What does " heat up" mean? Is the water temp getting high on the gauge and then dropping to a somewhat normal range? Or is it that your a c blows hot air and then cools down? What sort of noise is it making? I'm assuming you replaced the belt already? Belts will go bad, sometimes quicker then you would expect, they can make a pretty good rattle themselves.

Probably 2 different clutches because there may be different compressor motors? If you're blowing no cooled air, check your compressor see if the clutch locks up when you turn it on, take 2 people for this, does it make this terrible noise on startup, with no a c on? Temp gauge running up and settling back could be normal, how far up does it go? Maybe time for a new thermostat, belts are not the quality they used to be years ago, do you drive a lot of miles, most belts only come with a 1 yr warranty.

Could be a multitude of reasons why no a c. Do you have anyone that could help you check out at least the a c? To check the clutch, you could actually do it your self. You'll need a short piece of wire, 14 gauge or so. Find your a c compressor, it should be down below the alternator and, or power steering pump. You'll notice where the belt goes around the pulley, the clutch is located right there in front of the pulley, next thing look at the firewall on the passenger side, maybe under the plastic shroud, you'll see what looks sort of like a bottle, black it will be, has an electrical connector on top. What you want to do to check if the clutch locks up is: start your car, put a c switch on max, unplug the connector previously mentioned, take your little jumper 14 gauge wire, hook it between the two female end in the plug, and watch for the compressor clutch to lock on, you'll see and hear it. If it locks up, at least that much is working, do NOT let it stay on, unplug the jumper, you may damage the compressor if it is low on refrigerant and oil. Your car must be r12 refrigerant, right?

The belt tensioner is making the noise? That's an easy fix, you shouldn't have any trouble finding it in a local auto parts store, did a quick search around here, all the parts are available, the pulley, tension unit and also the idler pulley. You can pull it off and try lubricating it, however it's got some pretty hefty spring to it, usually they're just replaced. Glad to hear it is something relatively inexpensive.
