Just a quick question to you all. I'm looking to check the pressure on the A/C system in my mother's Grand Caravan. I'm looking for the valve that I need to hook up my pressure probe too. She has a 3.8L model and unfortunately the manual does not point out anything about checking the A/C level. I've done it several times on my father's Oldsmobile Bravada so I am very familiar with the proceedures.
The only thing that looks remotely like the valve I need is on the front left side (looking from the front of the van). It's a little valve with a black screw on cap that looks like it is hooked up to the A/C system. The problem is that the pressure probe I have doesn't seem to want to hook up and make a nice seal. If anyone is familiar with the A/C system in the minivan I would greatly appreciate if you could tell me whether or not this is the right valve. It could be that I need to get a new probe if the connector is worn and isn't functioning properly. Thanks.
