I want to add a can of R134a to my TJ's A/C system. It blows cold but then shuts off after a few minutes. I bought a can of the stuff and the kit to put it in, but i cannot seem to find the low-side fitting! The fitting on the metal pipe that goes back from the compressor towards the firewall has the right fitting, but when I hook up a can to that, the pressure seems so high that it blows the coolant OUT of the can! OTOH, the fitting on the compressor itself is not the right size to fit ANY of the kits i have seen.
Where is the dang low-side fitting, or, what the heck am I soin' wrong here??
Thanks!!
