Thread: AC Recharge

I have a '92 GP and the air conditioner recently stopped blowing cold (except at night, lol...). It's hot down here in south florida, and I'd like to recharge the thing on my own. I can't find the low pressure intake valve to even see if I can recharge it with the kits they have in the stores. I already have the kit, actually, from my last car. I found one valve but don't think it's on the low pressure side. If I can't get to the other one, I have no basis for comparison. Is it under the battery housing?

Can anybody point me in the right direction?

i dont know about yours but mine is running along the firewall about midways at top back off engine bay ive got a 99

thanks beast, I think i found it near the underside of the air cleaner assembly. tight fit, and i need the r-12 conversion kit, but i think it's doable for a short term fix. not sure i'm gonna keep this baby too much longer

what your describing seems like the high pressure valve, do not mess with that. Go to back of engine bay, like below windshield, middle of engine, top of firewall-- kinda tucked back a bit below the lip. It should have a cap on it. If you are doing a conversion or with any diy ac recharge kit for that matter the fitting will only fit low pressure side to prohibit damage or injury to diy'fer

Thanks dude, I figured it out just like you said. I figured the valves they sell would likely only fit the low pressure side, and so it was. Got 'er fixed up yesterday. The valves were under the air cleaner near the base of the battery housing. The low side was the only valve that fit my hose connector, so I figured of the 3 adapters in the kit, that was the one that I had to use. Then I saw that it only screwed on to one of the valves, so I did that and charged her up carefully.
