Air conditioner locked up and broke the serpentine belt ... I am trying to replace it by by passing the air conditioner and can't find ant diagrams to do so. I do not want to use the air conditioner at all in replacing this belt.
Odds are you can't. The ac compressor is mounted in the belt routing so it would need the pulley to keep the belt tight.
You can get a used compressor from a salvage yard and mount it in place of your old part if necessary. It will allow the belt to run even if it has no freon in the system.
There are a few vehicles that a replacement dummy pulley was designed for, but I am not aware of one for your vehicle. Usually if you try to run the belt without the compressor pulley, it will rub against something or not allow the belt to run in the right direction.

You need to have an automotive technitian install a new belt because there is a certain path the belt must follow before it will go on, plus the belt must go around the A/c as it is part of the path. You just don't have to use the A/C.
Tell the tech that the belt broke so that he can look for a reason as to why the belt broke.

yes remove the wire plug off the front of the compressor near where the belt goes.If it is stuck take a pry bar and un stick it,do not put the wire back on.The clutch is maganetized and the bearings are froze up.Usually this will work. If not You will have to either get one from the junk yard and put it on.Or fix your car the right way.

Rather than by pass the AC pulley You can actually buy a dummy pulley. It has the same position and size as the the AC pulley but has a frame instead of the AC assembly. In this way you can remove the A and keep all belts etc. the same.
