1997 E420 Blower Speed Control

The Blower Speed controller on the Climate Control Unit only funtions for low speeds. It seems the push button controller has lost its spring. Can the push button controler be replaced or repaired without replacing the whole climate control unit? If so where can one be purchased.

Thanks
Gene

Welcome to Mercedesshop.com.
If you are referring to the actual controller in the dash, it is available seperately. There is a special tool (sheetmetal "keys") that are used to remove it. You should be able to buy both the control unit and the "keys" at this website (the "fastlane" and "partsShop" keys at the top of the MercedesShop home screen will direct you the proper area of this site. I understand the prices are quite competitive. I work at a dealership, so I don't have any first-hand experience buying here. Give them a try, or else your local dealership can help you also. If it seems like the button or buttons are mechanically defective, then replacement will be about the only cure.
