1) Disconnect negative battery cable
2) Removed the serpentine belt
3) Disconnect the connector that goes over the AC compressor
4) Removed the AC lines behind the compressor
5) Removed brackets attached to compressor going to side of manifold bolts
6) Removed the 2 bolts below compressor supports and your done.
Some things you want to keep in mind are; be sure to add the correct about of refrigerant oil directly into the low pressure side of the compressor before reattaching the lines and turn the compressor shaft a few times after adding the oil. Also an A/C evacuate(needed to get all the air out of the lines) and recharge will have to be done by someone with the required equipment. It's also a good idea to change the filter/dryer and expansion valve(if it's easily accessible) Since you'll have the system empty anyway and when compressors die, they normally get all sorts of metal shavings into yours system.

It is probably worn out and about to seize. Replace it before that happens so the system doesn't fill with debris from the pump.
What are ideas on how to bypass the AC compressor with the serpentine belt on a 1996 Blazer S10?
This is just a guess so take it with a grain of salt. I would buy a belt for the s10 without air conditioning and just bypass the air conditioning pump.
