I have never charged A/C on my 96 XJ before. The A/C never worked from when I bought it, but I never needed it until now. I checked the lines by pushing in a set of needle nose pliars into the fill points, and there was NO freon coming out--must be competely empty. I bought the kit with the reusable trigger nozzle and 2 R-134A cans. I started up the engine, put on the MAX A/C and went to go charge the system. I screwed on the nozzle to the can, shook it up and plugged the fitting onto the line. I go to squeeze the trigger, and it climbed up to 35psi in about 2 seconds.

There is no freon in the system....did I hook this up wrong, or is there a block in the line?

The system I bought was the Arctic Freeze and it has the dye in it to see if there is a leak. The package says to find a "white disc" in the nozzle and remove it before using it. I couldn't find any white disc, so I assumed it had been removed.

Now the nozzle is on the can, the can is full of 134A, and if I pull the nozzle off to take a look, I am going to make a mess of dye and leak all of that freon to the atmosphere.

Any ideas what to do? Or do I just go buy a new can and start all over?

 

I would pull the header panel off the top of radiator and look at the line that is screwed to the top of the condensor... if it looks ok.. look for a line that has oil on it or has a wet aperance..then after you find and fix leak then you need to have it vacuumed down..if you can find a leak then i guess you need to find someone that has charged one before..its not to hard..

 

You low side won't have hardly any pressure until your AC is on anyways, so checking it with the AC off isn't going to yield anything.
