http://www.mercedesdot.com/newsletter/issue8.htm There ya go. Its pretty straight-forward. That was the first thing I ever did to a car. Pretty straightforward, just a lot of baffling to go through. Also, check the fuse for the blower first. It is located in a little box on the front wheel mount. It is all by itself in this black box, not near the fusebox on my 300E. It is a flat fuse, mine was blown in addition to my blower being messed, took me a week to figure out what was wrong....
