Air Conditioning?

I have a 1998 GMC Jimmy 4 door 4x4, 4.3 liter, the air conditioning has not been working properly. It works off and on. When it is not working properly it blows out hot air. Often on days when it is really humid, above 90 degrees, it does not work. Just wondering if maybe it needs to be recharged, I wouldn't think that there is a leak, because on the days it does work, it works all day with no problem. Thanks for the help!

A lot of things can cause that type of problem, it's probably best to let a pro look at the A/C system.

The cooling system IS in good shape, right?
