HEY,look at the post i just did on ac heater box i just removed. i talked to a ac person here and they said you should replace the dryer (the cylender type unit on the inner fender. they said it breaks down with years of non use and can runit your other componets by trying to use it due to the stuff(salt) in it that makes it a drier. check the radiator unit and the dash unit by using less than 25 pounsa of air preasure and put it under water for leaks. vaccum does not show the leaks as well. if not leaks. you are in business. you must get a "o" ring set and replace all. they are located whereever a hose or fitting bolts together. use ac oil to rub on them before you bolt up. you can check your compressor, cluth etc. against lock up by crossing over the two wires on the dryer and the clutch will/should kick in and if not locked up you are good. put less ac gas in system than is called for due to old running higher than new 'freon" . of course do the vacc etc. you can get the loaner at autozone i think. that all i can think of right now. but should get you down the road a ways.
