    Solved! See new post(s).

    My 1999 Grand Prix GTP has had a bad A/C leak since I've owned it. (Bad as in it pisses all your 134a out in under an hour.) You'd think a leak this large would be easy to find. Today, I tried UV dye/134a combination and a small UV light. Nothing. Also tried the soap and water method, no bubbling anywhere.

    When I try listening for the noise, it seems to be very close to the accumulator. I saw some bright green UV dye around one of the connections, so I replaced the accumulator and o-rings and repeated the process. Again, noisy leak. Felt around with my hands around all the A/C lines, hoses, fittings and connections. Can't feel or see a damn thing. The only A/C part that I can't see well in the vicinity of the hissing is the condenser. I know the condenser is a big PITA to pull out to get a good look at, so hopefully that's my last option. Looking at the front of the condenser, I don't see any signs of leaking or damage. Nothing from the side as far as I can see, either.

    If you have any opinions, suggestions, or advice, please share.
