Weird problem. My climate control acts strange in my 98 E300. All fuses are ok though, and if I override the Auto (thermostat) feature, the fan and temp control seems to work. However, something just isn't right. I recently spent 2500 mi in the car over the holidays and figured out what is wrong: the passenger side controls affect the driver, and the driver side controls affect the passenger!! I know this is true, as I can turn off one, and control the other side alone with the opposite controls.

Gilly, other 210 owners or anyone else ever heard of this problem? According to the previous owner, the only work that has been done to the car was a replaced glow plug relay, so I don't think any one has monkeyed with the system.

Thanks in advance for any replies.
