Instructions for Cleaning Window Switch Contacts

Model: Mercedes Classe C W202 - Years 1993-2000
Part: Push button

The window switch buttons are located on the center console around the gear shift lever; to remove them, first take off the gear shift knob by unscrewing the collar at its base, then remove the trim that holds the buttons. Disconnect the trim from the button support and unplug the connectors. Remove each button from its support and clean the electronic circuit using contact spray and a brush or toothbrush as shown in the video to eliminate any signs of oxidation (if possible, reflow the solder joints with some gel flux). Proceed in reverse for reassembly.
