Is the auxiliary fan for 81-85 300sd's servicable? Is there a way to lubricate the motor? My fan just got a lot louder this past week. Is the fan motor able to be repaired like the heater blower motor? I have searched the forum long and hard but have come up empty.

When it wears out you replace it. I've never known of one being repaired or rebuilt.

Good luck,

The other day I had to tear my fan apart becuase it wasn't operating...at all. I figured it may just need some brushes or something since it still spun smooth by hand and all. Turns out, one of the bushes got stuck in its housing a LONG tim ago. So I have nearly mint brushes on a perfect commutator and am good to go now. BTW the bearings are probably going out on your fan..if I recall, they are ball bearings...front and back. If you can find a used fan that spins good or something you may want to do that...they are sorta weird bearings and probably not worth the time if another unit is available.
Best of luck.

Check HERE and see how to doit yourself of have it done. These can be rebuilt, or repaired.

The fan in my W123 body would not work. I was surprised to find out that the motor can be completely disassembled. Turned out a brush was stuck, and it looked new otherwise. I greased what bearings I could and put it back together, now it works great. I'd say it's worth a try to fix it yourself and save some greenbacks. If it has ball bearings, the seal or shield can usually be snapped out so you can clean and repack the bearing, then snap it back in.

I love it how so many components on these old Mercedes can be taken apart and repaired without having to buy new complete units, even items such as a trunk light switch. Great for the do-it-yourselfer.

It amazing isn't it how we have become a throw away society today.
