A/C cuts out when towing
#11
Started losing my A/C on our trip to SD last year. Heading up the Black Hills and it started cutting out on the hills. Worked fine while in the mountains. Started cutting out again on the way back down. Finally lost it completely by time we hit MN and hotter than He!!. Shortly after arriving back home in WI the A/C clutch went **** up and locked up. If the bearings are starting to go the clutch plate will start to get very warm. Dad noticed right away that the clutch was burning out. Color of the plate or something. Check yer clutch. As it gets hot it kills the mag connection until it cools off again. Curie temp and all that mumbo jumbo.
p.s. if it turns out the A/C clutch is fubar, you can swap it with out changing out the pump. Make sure you change out the armature as well since it will be toast...if it was a heat issue causing your failure. I couldn't find a replacement clutch anywhere, ended up getting a used pump and swapping parts. Works like new again.

**update**
I haven't been driving the 'Ole Dodge lately because of the A/C trouble. I got it out today, and same thing. The A/C will work just fine for 10-15 minutes, then compressor won't click on. So, drove it until it quit working, pulled over, jumped out and checked the wires going to the clutch. It had power on it. So, looks like I must have a bad clutch. I had the clutch only replaced on my Semi truck a couple years back. It even looks like the same compressor. Auto parts stores don't list a clutch for the Dodge. I might take it to the diesel shop to see if a big truck clutch is the same. Anyone have any ideas? Snod remarks? Bad jokes? I really want to get this thing fixed.
