Just picked up a 2004 GC Overland!
Just picked up my first Jeep! So far I've changed all of the fluids (engine, tranny, transfer case, differentials) and replaced the pinion seals front and rear. It was a lot of work but I knew about the seals before I bought it. I'm still trying to work out an A/C problem as it blows pretty warm. I took it to a mechanic who measured the high and low side pressures for me (175 high and 8 low) and told me it needed an expansion valve. Anyone have any experience with A/C and expansion valves?
Some pictures of my new ride after a good cleaning!

NICE!!!
You'll love it. Other than the blend doors (lost a weekend to that repair) and a window motor, I've never had any issues with mine in the four years I've had it...

Nice ride! I just ordered that valve from Rock Auto. $21 bucks give or take and will be replacing it this week. I have a thread rolling as we speak and have a q or two about the install myself. It seems pretty straight-forward.

The RB1 is a single unit in-dash AM/FM/CD/Navigation Radio.

It sounds like the pressure in the system is a little low. I would try charging the system with a can of refrigerant before replacing the expansion valve. Your low side pressure should be around 30-50psi and the high side should be around 2.5 times the temperature of the outside air. For example, if it is 100 degrees out your high side should read about 250psi. By adding a can, you will more then likely fix your problem.

A can of freon make take care it but your pressures are almost identical to mine when I added a can recently. Once I added it, it stopped my expansion valve up. The compressor would only run about 5 seconds every minutes because it was stopped up. I think I got some bad freon or it had moisture that went to the EV. Anyways, I replaced it, pulled the system down for 30-40 minutes and added 1 can of oil and 2 cans of freon(27 ozs) and it was good to go. So dont take the EV back just yet.

I agree. Just to clarify, this is what I said.
"I would try charging the system with a can of refrigerant before replacing the expansion valve."

Yeah I used the special mopar fluid in the t-case. The pinion seals aren't too bad if you have all of the right tools. I have never done one before but I just followed the instructions in the service manual and marked everything for re-assembly. The seal itself was a PITA to get out once everything was apart, I used a seal puller and a couple of different screwdrivers to work it out of the differential, it was really in there!

Yeah I tried adding a can and ended up tripping the high side pressure switch in order to get the low side pressure close to 35-40. I had to let some out in order to lower the pressure enough to get the compressor to kick back on and it still wasn't that cold. I might go ahead with the expansion valve replacement tomorrow and see if that fixes the problem.
