'94 & '95 years are the same AC compressor. Always check local parts stores, but also check RockAuto dot com price...+shipping cost but prolly no sales tax.

Go to the A/C Delco web site http://www.acdelco.com. Look up the compressor and then cross reference it to see what cars it will fit. Probably most GM's. If you replaced the first compressor because it failed and did not replace the accumulator, orifice tube and condenser and flush the lines, that is why the second one failed (as will this one) You must get all the debris from the failed compressor out of the system.

Buying a good compressor is maybe the most important thing you need to do besides making sure you service everything well. I went through a 4 year saga with our '90 Deville. Cadillac A/C systems are VERY touchy.

I was stupid, tried to save a few bucks, and replaced my leaking compressor with a reman one from Autozone. I wouldn't even buy a new one from a cheapo parts store unless you know what company makes the unit. Ready-Aire made the reman one that I got, whose clutch failed prematurely and melted the bearing and shaft seal when it overheated.

I found a good parts store that could get me a new Four Seasons compressor, and the thing has been running great since. It cost moderately more money than a reman unit, but it is built so much better.

I also tried the junkyard route. Always a fail with compressors. A/C systems are the first thing people let go and don't maintain on their cars.
