SHELBYGT NSM

I have a 1994 jeep grand cherokee, 4.0. 2 wd it has a little over 300,000 miles but i have taken extreme care of it . I have been using the R134 with the leak detector and found one leak it was at the compressor where the lines connect to it, fixed that just simple o ring replaced both of them, now the a/c stays charge alot longer but it still has a small leak but cannot find it, is there a common place to check, any info would help. I know it is getting cooler outside, it's something i would like to get fixed, Thank You,

If you don't see any signs of a leak at the condenser or lines, it could be leaking at the evaporator under the dash. It's a booger to get to. Don't use any kind of stop leak in it, that stuff is bogus.. just my opinion

I will take a look, also have another question, the place where you put the R-134 into the line, there was dye on it also but i dont know if it was from me putting the R134 in it or it is actually leaking. i know when i screw the cap back on the line after refilling the system back up to full charge, next day i would have to use channel locks to unscrew the cap, is that normal?

The Schrader valves and places where the lines connect are the main points for leaks.

Is there any way of fixing it or do you have to replace the whole line

Replace the Orings at the quick connections. No need to swap out the lines unless they're damaged.
