Well, after noticing that the fuse was blown I tried to spin it by hand it and didn't want to move at first.

Eventually, I managed to spin it and something sounded like it crunched or fell out of it and it started to spin but not really freely.

Then, I unplugged it and connected the plug to a power source and the fan spun but made a few squealing noises.

I have another fan that is the same size but actually is on a different frame.

I bought it for my '93 300D off ebay when I had it but that car had dual aux fans so I obviously couldn't use it.

I kept it about four years and what do you know...now I have a use for it.

I measured it and it has the same diameter as the fan that's on the car now and when I powered it up it seemed to spin faster.

When I spin it by hand it spins much more freely than the one on the car now but still not really free.

I guess for the time being I will take it off the frame it's on now and see if it will mount to the frame on the car.

All it has to do is stop raining...
