Anyone out there have any feedback on leak stopping products for air conditioning systems? The one I've seen is Stop Leak by a company called FJC. I have a Grand Cherokee (1995) with a leak somewhere under the dash. I like the idea of gambling $50 vs. $600 in labor to take out the dash and look for the leak. Question is, is the product worth the chance?

 

No, because the problem will not be fixed with gunk in a can. Fix it correctly or there will be problems later on.

Are you sure the problem is a leaky evaporator?

 

I've heard that the AC leak stop in a can are really good at stopping the leaks through the expansion valves and orifice tubes! LOL

Like Joe says, you need to go ahead and really fix the problem.
