The windshield wiper motor is a permanent magnet electric motor that runs the tailgate wiper. The motor speed is controlled via a switch with input from the driver through a wiper control module. The motor drives a pivot that moves the wiper arms to wipe clean the rear window.

This article will cover replacing the rear window (tailgate) wiper arm and motor on BMW E53 models. The wiper motor can be replaced in a few hours with minor disassembly of the tailgate. The wiper motor itself can fail, creating a situation where the wipers do not work or do not properly park. If you are having an issue with wiper blade chatter or streaking, try replacing your wiper blades.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users. Do you have questions or want to add to the article? Leave a comment below. When leaving a comment, please leave your vehicle information.

Disconnect the negative battery cable. See our tech article on battery replacing and reconnecting notes.

Working at the wiper arm pivot, remove the plastic cap (green arrow) by levering it off.
Figure 1

Working at the wiper arm pivot, remove the plastic cap (green arrow) by levering it off. I like to mark the position of the wiper arms using a paint marker. This helps to get the wiper arm in the same position when reinstalling.

Next, remove the 13mm wiper arm nut.
Figure 2

Next, remove the 13mm wiper arm nut.

Once the nut is removed, wiggle the wiper arms back and forth gently and lift it off (green arrow).
Figure 3

Once the nut is removed, wiggle the wiper arms back and forth gently and lift it off (green arrow). It should pop off the pivot. If it is stuck, use a battery terminal puller to remove the arm.

The wiper arm components are shown here: the arm, nut, washer (green arrow) and plastic cap.

The wiper arm components are shown here: the arm, nut, washer (green arrow) and plastic cap. Be sure not to lose the washer.

Remove the tailgate interior side trim panels.

Remove the tailgate interior side trim panels. Lever the panels off in the area of the red arrows. The right side is shown. The left side is similar.

Once you detach the trim panels, slide them out (red arrow) of the top trim panel and remove them from the vehicle.

Once you detach the trim panels, slide them out (red arrow) of the top trim panel and remove them from the vehicle. The right side is shown. The left side is similar.

After you remove the trim panel, check if the panel clips remained in the body.
Figure 7

After you remove the trim panel, check if the panel clips remained in the body. You can see one came out with the panel (green arrow) and two remained (red arrow). Squeeze clips and remove from body.

Remove the tailgate interior lights (green arrows).

Remove the tailgate interior lights (green arrows). Lever the lights out of the body. Then disconnect the electrical connectors (red arrow) by pulling them straight out.

Using a Philips screwdriver, remove the tailgate handle (red arrows) screws (green arrow).

Use a trim panel tool and lever the tailgate trim panel down.
Figure 11

Use a trim panel tool and lever the tailgate trim panel down. You are detaching trim panel clips (red arrows) when doing this. Be sure to lever in the area of the clips. Once free, remove the trim panel from the tailgate, disconnecting any remaining electrical connectors.

Disconnect the wiper motor electrical connector by releasing the tab (red arrow) and pulling it straight out (green arrow).
Figure 12

Disconnect the wiper motor electrical connector by releasing the tab (red arrow) and pulling it straight out (green arrow).

Working at the wiper motor, remove the three T30 Torx fasteners.
Figure 13

Working at the wiper motor, remove the three T30 Torx fasteners. There are two toward the glass (red arrows) and one accessed via a hole in the tailgate (green arrow). When removing the last fastener, be sure to support the wiper motor to prevent it from falling.

Remove the wiper motor from the tailgate.
Figure 14

Remove the wiper motor from the tailgate. Transfer over the rubber mounting grommets to the new motor if necessary. Install the new wiper motor and tighten the fasteners. Leave the wiper arm off for now. Connect the battery and turn the wipers ON then OFF. This will PARK the wipers. Install the wiper arm. Align your marks and then install the nut. Install the trim caps. Then reassemble the remaining items in the reverse order of removal. Once complete, check the wiper operation.
