Squeeking Interior Air Fan in '92 300E
 

My cabin air fan squeeks at particular times, now. Usually when I've got the slower setting chosen, and typically on cooler days. Is it an easy thing to get to the fan to lubricate it? How do I do that? Would that fix it, do you think? Or is it a blet going bad or somethig else?

Todd:
It's kinda buried under the wiper motor, kind of a pain to get to it. I'd recommend replacing it rather than going through all the trouble to get to it just to try lubing it.

Thanks Gillybenztech for your reply:

So if I do try getting at it, do I go through the engine compartment, or do I go up under the dash from the inside?

From your comment, sounds like I've got to get the wiper motor out of the way first? (Which sounds like I have to go in from the engine side.)

Do you know what a new fan costs, or where i can go to get one?

Thanks for your help!

FastLane (here) shows A/C blower moters with and w/o fans for $296. I suspect the cost at a dealer would be more.

As Gilly said, the blower motor is under the windshield wiper assembly annd motor, and apears to be a job that's not too difficult, and may take 2-3 hours.

I've experimented a little with disassembly of the wiper unit to look at the blower motor, and it's not impossible for a DIY'er to do it.

To take out the wiper motor, you first open the wiper arm cover, loosen the hexagon socket screw, and remove the wiper arm. You then unscrew the 4 hexagon nuts, take off the retaining clip, unplug the electrical connection, then take out the wiper system unit. Then, you unscrew the hexagon nut of the wiper motor shaft, take off the crank arm with the attached linkage, and then unscrew the wiper motor.

Once the wiper motor is out, you can see the cover for the blower motor. The cover appears to be held in by clips. You can also see the outside air temperature sensor that you'd have to unplug.

Once the cover is off, the blower motor comes out. I didn't pull my motor out, but I'm guessing the motor justs rests in there and can be pulled out.

Good luck.
