Hi all... I have a 1998 E320 4matic that is now experiencing the all-too-well-known failure of the climate control blower speed controller. I've read numerous threads here about replacement of this component (OEM versus after market, using the controller from a W140 to keep from replacing the blower, etc.), but I haven't seen anything about whether anyone ever tried to repair the controller at the component level. Has anyone tried this?

Obviously, I would consider this because I'm cheap. Granted, it's not practical to repair some electronics, but sometimes it pays off. I did the capacitor clock repair on a W123 many years ago (before the Internet existed), so I'm not beyond trying. I will say, though, that this website would have saved me a lot of time back then, since I replaced the chip too.

Anyway, unless someone says something to discourage me from trying, I'm going to break this thing open and see what falls out.
