I am pretty sure the AC compressor on my 19 year old 560 SEC simply has, just totally, seized up.

It threw its belt, so that when it let go, it whipped around the one for the alternator and tore that one to pieces, too.

Replaced both belts and it did the same thing again 2 days later.

So...


The car is now running on the alternator belt only, and the HVAC one is off, for the winter, don't need AC for this snowy weather, and you can now see where the now bare AC pulley has rubber all over it from where the belt could not move and fused itself to the pulley.

I will be waiting to warmer weather to buy a new HVAC conpressor and another belt to try and take care of it.
