Wife and I were on our way to the Mopar Show in Shreveport Louisiana when we had a "incident".   We were west bound on I-20 @ 70 mph and wife said she was getting hot and turn on the AC. Wanting the gal to live in peaceful bliss.......I turned on the AC. In a few seconds the Comanche was blasting out cold air.   About 20 miles out of Shreveport we dropped off the super slab for a pee stop. Back at it in a few minutes and no AC. Just hot air, couldn't even feel the compressor
