Hello Sam,

I just replaced this myself. I even bought the car with this defect and learned from mercedesshop.com on how to change it. I used this to negotiate a lower price on the car and I got the part for $320 from Phil. My local dealer wanted $1100. Note that our year the regulator is not being built anymore and a dealer will replace the regulator, fan, fan housing, etc. Basically update it to the newer units in 1998+. I went with the unwired product featured here since it is an aftermarket regulator which does not require replacing all these parts and it does make the fan blow very hard on high. That is why I bought it, I live in Arizona which hits about 115 in the summer. You can also get a new one from silverstar recycling in Rancho Cordova CA for $250. They claim it is our year and brand new.

Anyways with a screwdriver and I believe it was a torx head and about 30 minutes you can get this done. Located under the dash on the passenger side. Might as well replace your cabin filters also. I found out this is behind the glovebox, glovebox comes out with 4 or 6 phillps screws. The glovebox comes out and a small door holds the two cabin filters which can slow down air recirulation if dirty. They are bright white brand new. I had leaves in my old ones!!!

Hope my experience helps.
