W210 blower (W140 retrofit?)

[dukegrad98]

A year or so ago I did the retrofit on the W140 blower fan regulator into my W210 chassis. I can't find the great illustrated how-to on that. Anyone help me with a link?

Also, that was a 1998 model. A coworker wants me to fix her 1999 E300, VIN# WDBJF25H5XA918522. It exhibited all the same issues as mine -- sporadic fan for a day or two, followed by no fan at all. Same song, second verse for her car?

Thanks for any tips -- hope to knock that project out this weekend.

Cheers, John
