I recently purchased a 1997 Dakota 5.2 L auto 4x4. 188000 miles and it is in great condition and has nice cold air. When I run the AC for about 30 minutes and either switch the fan settings or kill and restart the truck the AC clutch stops engaging. By the end of work or in the morning the AC starts right back up. I have checked the fuse and changed the relay. Any ideas? Thanks
AC cuts out.

This may not apply but when I worked at Subaru we used to get cars now and then like this. What would happen is the clutch and electronics in the compressor would overheat with the hood closed causing the clutch to stop working. If we ran those cars with the hood open the ac would work normal and never shut off.
The only fix at the dealer was to replace the compressor. Like I said idk if this applies to you but it sounds damn close to what we did at the dealer.

That's very possible. It could just be the switch for the clutch. I'm sure that's what it was at the dealer too but there were certain repairs they wouldn't let us do.
Like the ac Compressor for just a switch. And if a rear drive shaft needed u joints Subaru says it's not serviceable. So we'd have to replace a 7-$800 drive shaft instead of $20 for u joints. Lol stupid stuff.

Didn't even think of that. I always over look the easy stuff for some reason. Makes sense though. Since it cuts out when you try to change speeds.

Ok, I think I know what's up. I took it out and made it quit on me then I tested the high and low sensor connectors and the connector for the clutch. All of them gave 13+ volts. So I used a screwdriver and very carefully touched the clutch to test for magnetism. Sure enough it pulled, so I even more carefully(not much room between the fan and the front of the clutch) gave the clutch a smack with the plastic end of the screwdriver and it started spinning again. If I am right, that must mean there is something causing the clutch to stick when it heats up. I think I will try to replace it with the one on my donor truck which, barely blows cold but, seems to run constant.

I switched out the clutches and it seems to be working now. The temps have fallen by a good 10*F so that might have something to do with it but hopefully it was just that clutch. By the way, good thing I have the donor truck because when I looked for a replacement all I could find were Mopar $200 ones. Now to make my next thread...
