New AC compressor for my 93 Ranger was $156.
There is no Air Compressor on a 1988 Chevy S-10 Blazer. I'm sure they meant the A/C compressor. And if you're not licensed to handle refrigerant you should take it to a mechanic that is since the lines will have to be disconnected to remove the old one and install a new one. Not to mention putting it under vacuum and recharging the system. The compressor is about $150 at Auto Zone, but removal and replacement rates vary.
5qts with new filter.
If you only replaced the compressor, 2 to 3 ounces.
you can purchase retro kit at your local parts store. Be sure to follow the instructions. If you mix r134 with too much r12 oil it will copper coat the system and lock up the ac compressor.
