Re: Serpentine belt snapped 2 days in a row, the belt was...
A burning belt usually indicates a seized idler pulley on those gm cars. You will have to find which pulley is seized and change, it before replacing the belt or the new belt will only burn and snap again.

serpentine belt is getting old and hard and the cold weather was causing it to slip
check belt condition ( small cracks across the grooves = scrap and get a new one) and check tension
Yes the pump should turn freely it could be the output shaft bearing or the compressor is out of oil. the best bet is to get a belt that will fit everything but the air compressor this will give you time to find the money to replace the pump and repair the AC systems. by passing the A/C won't hurt anything it will allow you to run it without A/C/ till you can fix the pump.
Any bearing mounted pulley can "freeze" if a bearing wears out. The most common result it it can burn up a belt which will break with the engine running. When it snaps it MIGHT damage anything it hits - usually with no bad results. ANY bad pulley (or pulley driven part such as the alternator) needs to be replaced before a new belt is installed or the new belt will be damaged from the friction. To replace the serpentine belt - there should be a belt routing decal on the underside of the hood or on the shroud covering the radiator.
Probably wet electrical components. Use an air hose to blow everything off , and let it dry good before you try it. Or, the mass air flow sensor could be dead.
