'92 300SE

Noticed a peculiar noise this AM when pulling into the garage @ work. Either the bearings/bushings are gone, or there's something wedged in at the rim of the driver's side aux fan. Fan still turns when powered by 12v, but makes a considerable racket. Turn car off, fan turns rough by hand - doesn't free-wheel at all like the passenger side fan.

I've pulled the power to the driver's side fan until I can determine what's the cause of the noise.

I'm assuming this will just result in higher engine temps if I get stuck in traffic, plus a little reduction in A/C performance.

Any other items I should worry about?

Thanks
