OK AC experts. I went for it and dumped the super seal stuff from WalMart. Now I have a very interesting scenario with the AC. After the super seal I charged it and tried to see if it was cooling. My low pressure side shot up to about 150+ PSI and would not come down. Tried to run it down the road to see if it was because of the lack of fan running. No cool and the compressor got very Hot. Not knowing what to do I dumped the pressure on the low side to about 5 PSI by hand. Since I had a partial 20 OZ can of 134 left this last weekend I said what WTH and dumped it back in to see what would happen. It took the charge this time but still no cool and the low pressure side does go down to about 30-35 psi. The interesting part is I can feel the cooling of some of the lines running from front to the cab. I think is actually the wrong line that is getting cold. The non-insulated line that comes from under the battery to the condenser I thought was the hot line and the insulated one was the cold line. Currently when you start the compressor that is reversed. The non-insulated line gets very cold. The other one nothing. Pressure on the low side always starts very high then comes down after you start the compressor.

Anyway the compressor is doing something if there is some cooling occurring. Just not in the cab where I want it. Anyone seen this before and can tell me whats going on?
