How do you change a door solenoid on a C220 Mercedes?

This is a plug and play installation. The door trim will have to be removed for the door(s) that have bad lock actuators. Once removed the motor assemblies and control solenoids can be accessed. The solenoids will have a black wiring harness attached. This can be quickly disconnected and the new actuators replaced. If connectors are dirty or contaminated they can be sprayed with electrical parts cleaner first.Ê
