ac clutch
I'll have to give this a shot..............tomorrow. 94 and humid today in Michigan. The info on this site is priceless thanks to all the wrench heads. I'm more of a fix it when it breaks weekend mechanic! But with all good info, I feel pretty comfortable doing it.
I figure If it breaks, it had to replaced anyway!!
Have a great summer!!

So I tried this today. My clutch would engage for about 5 seconds then disengage, it would keep cycling like this. Measured the gap and it was too much. removed one shim, put it back together. has a gap of about .024. but is it is still cycling as before. Any suggestions what to try next.

I don't think mine is cycling at all. I check my gap today and it is good and it works like it is suppose to when you turn the ac on and off. But for the life of me I have yet to hear or see it cycle with the truck running and the ac on. Do I have a bad sensor somewhere maybe?

make sure that the ignition is on but engine not running. with mine I was able to turn the key to on and turn the ac to max and I could here the clutch engage and disengage if I turned the ac off.

Open hood, insert feeler gauges, read them.
Determine if the gap is too wide. Fix it if it is. Check afterward.

My truck's a/c works fine when driving, but turns off when I slow to a stop. I measured my clutch gap at .40 and when I took out the shim/washer it was .10. Clutch seems to be engaging and disengaging fine. What's the biggest issue for having the gap at .10 other than the clutch not disengaging. If the the clutch disengages and engages, I should be fine rt? A/C is blowing cold, would it blow less cold with my current setting?

In reality, the spec SHOULD be "as small as possible without any hint of touching when disengaged".
I have set one as low as yours without a problem. It's just not a good recommendation to be that small, as some might shoot for that amount and dork up their clutch because it rubbed, even slightly.

I'm going to test my a/c for the next few days and look for a .15 shim. Looked all aver my shop and could not find one that thin. If it works fine, probably just leave the gap at .10.
I belong to a few other car forums and this one is one of the better one's.

Thanks for saving me a bunch of coin! Love this site!
Hopefully it'll keep working on the way up north today!
