It has been very cold here in Minnesota and coming out of work today and driving away I noticed the blower wasnt operating. . Now what? Voltage on climate control read 6.0. where are fuses I can check? I know on my old 90 300e this happened and it was a fuse. Any guidance is appreciated.

Your issues are with the fan motor itself or fan mounted voltage regulator---remove the glove box and start to do some testing or throw parts at the car!!

It might be a good thing to check the stickies and get into the top of the blower where the regulator is - you want to check the "type" of regulator before ordering parts.

MB discontinued the "original" regulator - which I call "flat face type - and MB parts side list now list both a new/different blower and it's matching the "new" regulator that call " tytpe"

On "original"/flat-type regulator replacement there is a thermal silicone that goes between the "flat" original; regulator and the blower top plate...

"Some" purists buy the MB brand part for the W140 series - which is the same MB part as used on the original W210 - but the leads are different length - and requires splicing plus buying computer-chip-thermal paste (like $4) to properly mount.

This eBay listing below is for a China made "original" regulator - shipped from CA - with correct W210 wire harness - and as a nice touch includes the thermal goo - for $20.
