The ac is blowing a little cool air and i know it is low on coolant. And my question is where is the fitting located to put more coolant in it. I've looked on all the lines and could not find the valve to add the gas. So is there some place they put it or what is needed to get AC charged.
CALL THE CAR DEALER AND ASK THEM WHERE IS THE VALVE TO FEED THE FREON AND FIND OUT WHAT TYPE OF FREON.

You need to follow the ac lines from the ac compressor to the ac condensor to the fire wall behind the engine where it goes to the heater box.There are two connections,both at differant locations,a low side that has a screw on red or blue cap with the letter L on it and a high side with a cap that has the letter H on it.The refridgerant goes into the low side.Hope this helps.

What you will be looking for (in your engine compartment) looks almost like a large valve stem that you would see on a tire. It will probably have some kind of plastic cap on it.
It shouldn't be that difficult to find. You may want to search for an engine compartment diagram for your make/model/year vehicle.

Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry

Look for the accumulator(silver can a/c lines go to) on the passenger side of engine area. The Low side charging port cap should be on the side of the accumulator.

Your A/C sounds like it needs to be vacuumed
out and then recharged to factory specs. That
should solve the problem.
