Recharging a/c on fl112

[bryanbrown]

I have an fl112 with a c12, and the a/c isn't blowing cold. the compressor comes on when I hit the switch, it just doesn't get cold. I found the small fitting to fill it, like on regular trucks. Will That work? I'm assuming the small one is the low side and big one's the high side, like a regular truck. thanks

yes sir. Should be no different. only thing that big truck will probably hold a lot more freon.

Make sure to check you cabin air filter if equiped and wash out the evaporator and condenser really good before you try and charge it. Depending on the ambient temp outside you should have about 30# on the low side on a fair day and 35# on a hot day. If you have a way to check the high side it helps, if the high side pressures are really high and the low side normal you have a blockage or orrifice tube clogged.
