Low speed fan problem....89 300E

Only recently I've noticed that my low speed fan button, when pressed, does nothing. The only way to activate the low speed fan is to turn on the high speed fan (or auto button), then press the low speed button.

Any ideas?

Sounds like the blower motor has high friction in the bearings. Needs lubrication or new bearings. Old motors do this and they wont run at slow speeds.

Justa thought.

That makes sense. Where is the blower located? Is it easily accessed for a well directed shot of WD-40?

Personally, I'd be tempted to replace the motor if I went to the trouble to access it, but some have had long-lasting success by lubricating the bearings with ATF.
