Just returned from a run from San Jose to LA. Here are the A/C results.
Going down I-5, another example of a perfectly good highway, ruined by politicians stealing the money to buy votes instead of reparing the road. Must work, Democrats rule. But, I digress;
Speed: 68 mph, on cruise.
85 outside, 40 vent temp, 72 inside. Fan at #1
later, in LA;
98 outside, 39 vent temp, 70 inside. Fan at #3
Thought I'd see what would happen at MAX. My ears got cold and it was noisy. Vent temp never went below 40.

Discovered the cause of the hellacious grinding as I pulled off the freeway. A/C clutch bit the dust.
I am eternally greatful to Dodge (and Denso compresser company) for a vehicle that got me home, and not breaking in LA's 98 degree temperature!
They are supposed to nickel and dime you, when they get to high mileage; this will cost almost $700.00.

Shatto, hey man, don't pay $700 for replacing the A/C clutch. It's not hard at all to replace. Just takes time and most clutches come with instructions. The hardest part which isn't hard at all is adjusting the air gap. Once you get it on you have to "burnish" the new clutch by cycling it on and off about 10 times. What probably happened is the clutch bearing went bad and caused play in between the moving parts. I just went all out and bought a vacuum pump, manifold gauges and other things. The reason my A/C wasn't working is because my orifice tube was clogged. I changed it and it worked fine.

Shatto, if your truck is indeed a 98, that happens to be a fine Sanden produce, not Denso.
You can change the clutch assy without even blowing the charge on the 3.9/5.2/5.9 equipped ones. All you have to do is unbolt the compresssor from the bracket. A little cumbersome, but saves the time and money from getting it recovered, evacuated and recharged.
Any of the big part store can get the kit - and it won't cost you anywhere near $700.

I'm having problems with mine also. It makes alot of noise when my AC is on. I was thinking the clutch is goin out too. Not looking to spend $700 on a new AC so that left changing the clutch. I found some directions on the following link.

Maybe I read the name on the alternator.
Thanks for the advise, gentlemen.
I followed the advise of my mechanic who explained that Something would as likely get broken trying to remove the clutch and he'd have to replace everything anyway. Also the fact of 500,000 miles on it; getting old, you know, plus the theory that if the engine ever wears out I could do the "short-block" thing and put a new compressor on it.
The $700.00 included a refill of the Explorer, loaner I did courier work in for a day. What's that, about $100.00 by itself?
