If your seals are shot and the coolant is leaking out you'd see an oily residue. 95 I believe is the new R-134a. First off you have to see if the clutch engages on the compressor when you turn the A/C on. Turn the A/C on and visually look at the pulley. Is the whole thing spinning or only the outer? If the whole thing is spinning then the clutch is good. If only the outer then the clutch isn't engaging. If the clutch isn't engaging you'll have to find out if it's not getting the input or not.

If the clutch is engaging then I'd go to the parts store and buy a charge kit they're cheap. Follow the instructions to service your A/C. If that works and doesn't hold then you have a leak somewhere.

Since it is a 95 my money is on the clutch isn't engaging cause it's shot. Unfortunately the only fix for that is a new compressor.

Let us know what you find.
