2001 S 430 W220 blower motor noise- Steve B, MB DOC...
 

My blower motor sometimes makes a little bit of noise depending on the fan speed for the last year or so. It seems to be getting slightly worse. This may be from water filling the outside drain and spilling into the car a year or so ago. Can I pull the motor and lubricate( even repair? ) it with ATF or some other good lube or do I need to buy a new motor to fix the problem?
Thanks

A lil shot of silicone spray where the squirrel cage fan connects to the motors driveshaft solved an annoying squeak on my 99.

a couple of things can be going on here. if there is a leaf stuck in the blower motor it can cause this problem. just remove the blower motor and clean all the stuff out. alos you might want to replace the cabin filters also. secondly if water got in there and there is rust all over the bearing on the blower you are better off just replacing the motor. check in the engine compartment where the fresh air goes into the cabin and see if the drain on the bottom is plugged. this happens quite often and can be a real problem. water gets into the passenger compartment and goes all the way back behind the passenger seat and takes out the rear sam module. this is only in some cases. hopefully there is just a leaf stuck in there. hope this helps

doubt leaf
 

Does not sound like a leaf.
the drain was plugged earlier but not I keep an eye on it-good advice though
Is the blower easy to get out on the W220s
Thanks
