what happens when u just turn on the defroster?

The car did again and was able to test the defrost and the fan does not work in defrost.

I find that mine sometimes will indicate full "throttle" on the fan speed indicator but the fan is just wafting along. Then, after a while, it roars to life for a while and quits.

I think it's the blower driver/amplifier going south.

Interested in info about verifying full 'climate control fan' performance in our W210. Clicked on this thread not knowing what it was about.

May I suggest the OP consider editing the title appropriately?

Perhaps: "96 E300 W210 Blower motor intermitent operation."

Year/model/ chassis/ issue.
