M1152A1. Pic is taken from the passenger side. This cut harness is right next to the seat. I tried to find it from under the truck but could only see a little section of it. There are two red wires and two black wires that go somewhere.

I did some searching and reading but am not quite sure where to start. New (to me) M1152A1 with factory AC. Heat works fine. When I flip the switch to AC, nothing happens. Looking at the compressor, it doesn't physically engage. Of course, the seller said the AC worked. If that's true, then it...

New (to me) M1152A1, this thing is in the engine bay, right in front of the driver. It's been unplugged since I got the truck. Google says it's a 'time delay module' for the cooling fan. Truck seems to run and drive fine. Should I leave it unplugged or plug it back in?

So I bought this 2007 M1152A1. It was delivered today. The truck seems to run and drive well (though I've only driven it for about 30 minutes). Everything appears to work and feels tight and responsive. https://bringatrailer.com/listing/am-general-m1152a1-hmmwv/ A few questions: 1. The...

Thought you guys might get a kick out of this short action movie I made. I wanted to shoot something revolving around the HEMTT so this is what we came up with. :LOL:

Looking at buying a HMMWV from a local PD. They don't know what motor is in it and I'm new to HMMWVs (previously owned a HEMTT but never messed with HMMWVs). Can anyone ID this for me?

(See post #73 for solution) All of a sudden my M978 HEMTT w/ 8V92 diesel won't start. It cranks over fine and on the first turn it will sort of cough or sputter a little like it wants to go, but then it just goes cold. If I wait a minute and try again, I get the same result - a tiny sign of...

Anyone know how to adjust HEMTT front wheels / steering alignment? I have a side-to-side shimmy when out on the highway and I think it's because the two sets of front wheels aren't aligned very well. When the truck is parked straight you can visibly see the wheels not quite pointed in the same...

Any idea why my M978 HEMTT is leaking transmission fluid from the breather vent on top of the trans while running? I'll be driving the truck, come to a stop, and it will be dripping down the side of the trans, onto the axle, and onto the ground. It's enough that it's a problem (I don't want to...

M985 HEMTT won't build any air pressure. Starts and runs fine, but will not drive as the brakes (and apparently throttle) are air actuated. Air pressure gauge reads zero. Thinking compressor but can't find any spare replacements. But maybe it's not even the problem. Any ideas?

Anyone on here have a M1120 HEMTT LHS? I could really use some close-up pics of the hook lift assembly, specifically the area around the transfer case, if possible. Would be greatly appreciated. Let me know! Pic from Google:

We've got a M985 HEMTT that we're trying to swap a complete hook lift assembly from a PLS truck on to. We removed the tank and the front mount appears to be very close (certainly close enough) for the hook lift to bolt up to. The rear mount will need modification. But the big problem we're...
