Re: Seized ac compressor, can I bypass with ashorter...
If the compressor itself has failed, you can unplug the clutch and leave the belts as they are. If it is the pulley bearing that failed, replace it, it does not cost all that much.

no
disconnect the power wire to the ac compressor clutch
that will isolate the compressor if it has seized bit still allow the pulley to turn
if it will still not turn , have the pulley removed and a new bearing fitted
more information would be advisable year make model engine --if you have a serpentine (a single belt )leave belt on unless compressor is stuck seized because all other accessories will be affected if compressor is by it self can remove with out problem it wont affect your defrost in winter
If the compressor is seized, you will know when you turn on the AC, as the belt will shriek like a banshee usually. And yes you can usually just bypass it with a belt for the same model as yours without AC. If there werent any built without AC, you can try another model with the same engine. If all else fails, you can use a small mason's rope to pass through the pulleys without the AC and mesure the length of the rope needed to do so, then count the number of ribs on the original belt. Any good counter parts guy will be able to find you a belt that will fit the measurements as close as possible.
If the pulley on the compressor will not turn freely, then yes if a bypass pulley exists you would need to use it in place of the compressor. If the compressor pulley turns but the compressor is locked up, just unplug the compressor clutch.
the defrosters run with the ac compressor running whenever its 49 degrees and higher. it does that to get rid of humidity faster. the pulley works off the ac clutch behind the pulley so you have a locked up clutch. find a belt to fit by bypassing the ac compressor will do if you like
TAKE A ROPE AND RUN IT AS IF IT WERE A BELT ALONG THE ALTERNATOR AND CRANKSHAFT. MEASURE THE LENGTH OF ROPE THEN GO TO PARTS STORE TO BUY A SMALLER BELT. THE IDEA IS TO BYPASS THE AC BEING A 94 IM SURE IT HASN'T WORKED IN QUITE SOME TIME, I'VE BEEN A MECHANIC FOR 8 YEARS AND WE BYPASS THESE ALL THE TIME, THE TENSIONER ON THAT CAR I BELIEVE IS ON THE ALTERNATOR, HONDA MADE THE AC OPTIONAL.. BELTS ARE USUALLY NAMED AFTER THERE SIZE (IE 4060934 IS 93.4 INCHES LONG) IF NEED BE REMOVE THE AC COMPRESSOR.
