My name is Ryan and i own a CLK 320 2002. For some reason my windows will only work is my headlight are turned on. What could be causing this?
Have you had any work under the dash done? Wires may be incorrectly connected. The window wires should be connected to the ignition switch so when the key is turned on, power is sent to the window circuit. If the wire somehow is put on the headlight switch, and power is added to the lights which activates the windows, than the wiring is wrong.
