my ac seems to be working ok.I get it to about 42-44 degrees on setting 2, when I turn it up to setting 5 it seems to loose is coolness. Ive been using a candy themometer to test it and it just doesnt seem to get cold enough. My wifes grand caravan get to about 36 degrees. It takes my truck a good amount of time to reach 42-45 degrees. How cold should it get and how do I locate the low pressure side so I can recharge it if needed?What else could cause it not to get colder?

Hi,

It sounds like the system is a little low on Freon, Here is a diagram on where the low side port is which is on the side of the accumulator, and here are some guides that will help you charge the system correctly.

there are two hook ups on the high pressure side; I think. The ac is blowing hot air, and the compressor is working. I just want to charge the system. But I can not find anywhere to connect the "walmart bottle and gage", it will fit on one of the connections on the high pressure side, it reads in the read while on or not, higher when not. Can you help?
