1994 Sable 3.8L A jammed A/C compressor and or clutch assembly caused
the pully not to rotate so it burned through the serpentine belt. 1)
Trying to avoid spending a lot because the car is over 200,000 miles. I
do not need A/C. Is there a way to free up a frozen A/C compressor and
or clutch so the pully will rotate. Or is there a way to by-pass the
A/C unit with a shorter serpentine belt?
Maybe a guru will have a way to bypass the compressor, but short of that the
A/C needs to be freed up. I can only speak in general terms...
The A/C problem is that the bearing in the clutch has seized. (If the
compressor seizes, the pulley still turns freely when the A/C clutch is not
engaged.) Usually the bearing is considered an integral part of the clutch.
Even when it is separate the rest of the clutch is too old to keep - sad
experience there. The good news is that replacing the clutch is usually
affordable (depends a lot on accessibility) and does not involve messing
with the refrigerant. If the compressor is accessible and there is enough
room in front of the clutch, it may be a DIY job if you are up to it. Clutch
removal typically takes a special but inexpensive tool, while it normally
just bolts back on.

IIRC, NAPA sells an idler pulley that replaces the a/c
compressor and uses a standard belt for the engine. The
problem you descrobe suggest a seized pulley bearing. If
the pulley bearing is not seized, you should be able to pull
the electrical connector at the clutch. If it then turns
freely, it is the compressor seized. You can leave it
disconnected but your defroster won't be worth much since
they depend on the a/c to dehunidify.
