How to replace a Mercedes-Benz 190E 260E 300D 300TE Front Left Seat Control Switch?

1.Materials Needed

Protective gloves
Repair manuals (optional)
Safety glasses
Screwdrivers
Trim panel tools (optional)

2.Locate the Seat with the Faulty Power Seat Switch & Pry Out the Locking Tabs

Using a flat tip screwdriver, slightly pry up all around the switch base or cluster. Pop out the switch base or cluster and remove the harness from the switch. Using a small pocket flat tip screwdriver, slightly pry on the locking tabs on the power window switch. Pull out the switch from the base or cluster. You may need to use needle nose pliers to help pull out the switch. Get electrical cleaner and clean out the harness. This removes any moisture and debris to create a complete connection.

3.Removing the Power Seat Switch

Disconnect the negative battery cable and set it aside. Remove the trim panel retaining screws using a screwdriver. Then pull the seat trim panel away from the seat cushion in order to release the retaining clips. Using a trim panel removal tool is optional.

Using a screwdriver, remove the screws that hold the switch panel to the trim panel. Remove the switch’s electrical connector by pushing down on the tab and sliding it off. Then remove the switch itself.

4.Installing the New Power Seat Switch

Mount the new seat switch in position. Reinstall the electrical connector. Using the same retaining screws you removed earlier, attach the new switch to the switch panel.

Mount the seat trim panel in place. Then, insert the screws and tighten them down using a screwdriver. Reconnect the negative battery cable and tighten it down.

5.Check the Power Seat Switch Function

Turn the key to the on position and press on the upside of the switch. The door window should go up to the door open or the door closed. Press the downside of the switch. The door window should go down to the door open or the door closed. Press the cut-out switch to lock the passenger windows. Check each window to make sure they are locked. Now, press the cut-out switch to unlock the passenger windows. Check each window to make sure they operate.
