Air Conditioner leaks, where???

[Archive]

I seem to have a leak but for the life of me I can't find it. Started with soapy water and
graduated to dye injected in the low side port. Went over everything under the hood with a fine tooth comb and still can't find the " freeeck'in " leak.....
What have other people come across as far as what leaks they've had. Since I can't find any trace of the dye leaking out, I'm wondering if the condenser (heat exchanger? under the dash) is the culpret. I thought that if this was the case, I'd atleast see some dye coming out of the drain tube, but nothing was found.
I've gone through 32 oz. so far and I've got to find the offending part. The leak is bad enough that my air only works for a few days and then it's out. Thanks... .

Facing the engine from the front, the sensor down on the left side of the engine just off the bottom of the radiator. The only way I found it was that there was a small amount of oil. It would slow leak. Dealer replaced it. That was my 98. No problems on my 01. That was leaking through the sensor, not the threads.

How about going to a refrigeration or AC shop and have the tech use his freon sniffer on it. Those things can detect leaks down to parts per million and most shops will do it cheap if not for free.
