Using a set of a/c gauges put the blue hose on the low side (suction side) and the red hose on the high side (discharge side) and make sure that there is no freon in the system and if you have freon in the system then you will have to go to an automotive a/c shop and have them reclaim it for you.. Put the yellow hose on your vacuum pump and let it run for about 1 hour and then let it sit for 1 hour so that you can see if it will at least hold the vacuum pulled. If so then let it run for an additional hour and then start the recharging process remembering to keep the low side readings between 30 to 40psi and the high side between 200 to 250psi depending on the outside temperature…………….

You can recharge your 1998 Mercury Mystique air conditioning system through the low pressure port. You can find the low pressure port on top of the air conditioning compressor.

How do i Recharge AC Unit for a 1998 Dodge Stratus
Buy the Hayes Repair manual and it details the procedure
2 reasons for the system to cut out, low pressure, and high pressure. I am thinking you are experiencing low pressure and need to recharge your system.
Take it to a garage that services ac. If it needs a recharge it must have a leak in the system.
Connect your Freon bottle to the low pressure port on your 1998 Chevy S 10 Blazer air conditioning compressor. Discharge the Freon into the compressor. A recharge kit will make this process quite simple.
Both high and low service ports are located on the top of the a/c compressor manifold assembly......
follow the compressor lines...and everyone should have a manual for their vehicle, and a professional shop manual should be available at the library in the reference section--you can make copies of the necessary information...good luck :)
