squeeky fan fix?

the fan on my 300e '88 is squeeking, i would compare it to the sound of fingernails on a chalk board etc., and it seems like a lot of digging to get to the fan motor itself and do it up nice to stop being noisy.

what if one puts the env. control unit into defrost and sprays aerosol lube into the intake vent by the wiper blade as the deforst runs? spare lube would end up on the windsheild, then wiped off and the motor would get some lube

or would this mess things up?

I have the same problem and will fix it one of these days. My understanding from my previous MBs and from searching various posts is that there are three basic options; gain access to the fan and lube it directly, gain access to the fan and repair it, or gain access to the fan and replace it. In any case, you've got to get to the fan first.

If you end up trying your system, and I will deffinitely let you try it first, make sure you post your results.

Your choices are:

1. Open it up and try regreasing (don't recommend due to time involved in pulling it out again if it starts squeaking)

2. Open it up and replace bearings if you can find a match. (good choice)

3. Open it up and replace with new blower (best choice)

There is no way you are going to get any lube on the bearings by spraying into the blower intake.

Don't spray into the vent - everything will be covered in the spray lube and as it gets older and a little sticky all sorts of dirt will stick everywhere and create a real mess down the road. Wholesale spraying is not a good idea. My friendly TV tech had a customer that had a slipping belt in his VCR that was squealing - to save money he tried to fix it himself. He took the VCR apart and sprayed everything with cooking PAM spray to stop the squealing. Of course the VCR did not work at all - it ended up having to be scrapped as repair was too expensive. Moral of the story - Get to the fan and do one of the three suggestions - in other words - don't go for the easy shortcut.
