Seems my HMMWV repairs usually ends up being one step forward, three steps back...
It was sitting for several weeks since the beginning of Inferno Season here in Florida. I cannot take the inferno anymore in my old decrepit state and if I do go outside with the intent of working on the beast, I end of drenched from head to toe after about 15 minutes, ending up totally dehydrated, and exhausted! Like heat stroke. Wish I had a tree I could work under. Helmet top won't fit in the garage.
When I left it, AC blew ice cold.
Eventually I felt guilty and decided I better go out and turn it over just to give it a bit of exercise. I started right it up, and I turned on the AC and I start getting a huge belt squeal noice as soon as I turn on the AC. Wife even heard it inside the house! AC blows hot to add to my misery. Belts were replaced last winter. Pop the hood and AC belts look ok, but compressor is fighting it rotating in a jerking manner. Belts seem tight.
A few days later it was cloudy and raining out so I go out and pop off the belts and I can fell the compressor pulley is rough with the AC engaged. AC off the magnetic clutch disengages and it turns normally so no squeal.
So I order a new compressor, which was cheap since it is an aftermarket system, PAG oil, and new receiver dryer since it is common practice to replace with the compressor. Bought the flush for the lines in case.
Wait a few weeks more and a hurricane comes through so I have a day of no inferno and between rain showers I swap the compressor and receiver dryer, and evacuate and recharge the system. Blows arctic cold

For once a successful repair. I check all the fittings with my leak detector and all fittings seem leak free.
Just went out now to take it for a ride over to drop off a package and fill it with dino juice. Starts out ice cold. Byt then end of the ride, it starts to blow hot air again.
I'll wait for a break in the heat and whip out the gauges and see what I find.
Always something with this beast!
