Summer is on its way, and once again my ac won't blow cold. Last yr we had it checked for the same reason. My bf took it to one of his buddies at the dealership, they charged it, put some dye crap in it to check for leaks..no leaks. It worked like a champ for about 3 months. I shouldn't be charging it on a 6 month basis should I??? We've checked all the obvious stuff, whats the deal???

Low side pressure line more than likely. Have you washed your engine lately? If not, great! Take a couple of pictures of the engine bay and post them up. Big ones! The better the detail, the better. You can usually detect a leak of that magnitude pretty easily, as the oil will leave a residue on the line when the R134a leaks out.

Haven't washed it, and I'll get some pics up soon. Thx!
