The windshield wiper motor in a permanent magnet electric motor that runs the windshield wipers via a linkage (transmission). The motor speed is controlled via a stalk with input from the driver through a control module. The motor drives linkages that are connected to a pivot arm that turns the wiper arms to clean the windshield. On BMW E60 models, the linkage runs multiple pivots to add stiffness to the wiper drive, and the wiper arm angle can be adjusted at these pivots.

This article will cover replacing the windshield wiper motor and linkage on BMW E60 models. The wiper motor can be replaced in a few hours with minor disassembly of the wiper cowl. The wiper motor itself can fail, creating a situation where the wipers do not work or do not properly park. If the wipers do not work at all, check that the wiper pivots move freely and are not bound with corrosion. To do this, follow the steps noted below. If you are having an issue with wiper blade chatter or streaking, try replacing your wiper blades or adjusting the wiper arm angle. See our tech article on wiper blade replacing and adjusting.

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.

Remove the engine covers and microfilter housing. See our tech article on engine cover removing.

Working at the left strut tower, remove the two Phillips head screws.

Next, remove the two 13mm wiper arm nuts (red arrow).
Figure 7

Next, remove the two 13mm wiper arm nuts (red arrow). The inset photo shows the right side pivot and arm. Note the notch to help when reinstalling. The left side pivot for the right wiper arm does not have this notch. Mark the arm position before removing it. Once the nuts are removed, wiggle the wiper arms back and forth gently and lift. They should pop off the pivot. If they are stuck, use a battery terminal puller to remove them.

Working at the left side wiper arm pivot, remove both plastic covers by pulling them away from the arm toward the left and then straight up.
Figure 8

Working at the left side wiper arm pivot, remove both plastic covers by pulling them away from the arm toward the left and then straight up.

I like to mark the position of the wiper arms using a paint marker.
Figure 9

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. Once you have marked the arm and washer, remove the 16mm pivot nut (red arrow). Then remove the washer. Next, you have to remove the wiper arm. What I do is open the hood. I then wiggle the wiper arm to remove it from the shaft. If you press on the wiper arm near the pivot it will loosen up. Then continue to wiggle it off. Be careful not to scratch the paint when the wiper arm comes loose.

Next, the pivot shoe (red arrow) has to be removed from the wiper pivot.
Figure 10

Next, the pivot shoe (red arrow) has to be removed from the wiper pivot. I like to mark the position of the shoe using a paint marker. This helps to get the shoe in the same position when reinstalling. Then remove the shoe using a battery terminal puller or a two-jawed puller (inset).

Working at the center of the wiper cowl, remove the plastic rivets (red arrows).
Figure 11

Working at the center of the wiper cowl, remove the plastic rivets (red arrows). Remove the center pin using a trim panel tool. Then lever the rivet body out of the cowl.

Next, rotate the 5mm Allen plastic retainers 90° counterclockwise to disengage it.
Figure 12

Next, rotate the 5mm Allen plastic retainers 90 degrees counterclockwise to disengage it. There are eight of them (red arrows). Then remove the two 13mm plastic nuts at the outer corners of the cowl (green arrows). Now you have to remove the wiper cowl trim. Start by grabbing at the right corner and pulling up, gently removing the trim piece from the mounting bracket located at the base of the windshield. Once detached, remove it from the vehicle and store it in a safe place.

Next up you have to move the center sir intake duct for the HVAC forward.
Figure 13

Next up you have to move the center sir intake duct for the HVAC forward. Start by removing the T30 Torx fastener (red arrow). Then directly below it (green arrow), rotate the 13mm plastic nut (inset) 90°.

Working at the right and left side of the intake duct, remove the two 10mm fasteners (green arrows).
Figure 14

Working at the right and left side of the intake duct, remove the two 10mm fasteners (green arrows). The left side is shown for orientation.

Move to the right side and remove the two 10mm fasteners (green arrows).
Figure 15

Move to the right side and remove the two 10mm fasteners (green arrows). The red arrow is pointing to the valve cover.

Once you remove the fasteners, move the trim cover forward.
Figure 16

Once you remove the fasteners, move the trim cover forward. Use a trim panel tool and lever it away from the wiper cowl.

Use the trim panel tool to hold the duct away from the cowl support (green arrow).
Figure 17

Use the trim panel tool to hold the duct away from the cowl support (green arrow). Then remove the four E10 support fasteners (red arrows). Then remove the cowl support from the vehicle.

Working at the wiper transmission, remove the T27 Torx fasteners (red arrows) in the order of the numbered sequence noted in the photo.
Figure 18

Working at the wiper transmission, remove the T27 Torx fasteners (red arrows) in the order of the numbered sequence noted in the photo. Lift the wiper assembly up and slide it out of the cowl far enough to access the electrical connector. Then disconnect the wiper motor electrical connector by releasing the tabs and sliding it off (inset).

BMW does not sell the wiper motor or assembly as separate parts.
Figure 19

BMW does not sell the wiper motor or assembly as separate parts. This does not mean there will not be an aftermarket replacement part. Or, you could be replacing the motor or linkage assembly with used parts from a donor car. Use the following steps to separate the motor from the linkage. Place the wiper linkage on a solid surface. Then remove the linkage from the wiper motor pivot. I like to use a trim panel tool to lever it off the ball joint (green arrow).

Then remove the lower linkage from the wiper motor pivot.
Figure 20

Then remove the lower linkage from the wiper motor pivot. I like to use a trim panel tool to lever it off the ball joint (green arrow).

If you are reusing the wiper arm pivot assembly, it is a good idea to inspect the wiper arm pivots.
Figure 21

If you are reusing the wiper arm pivot assembly, it is a good idea to inspect the wiper arm pivots. Once the linkage assembly has been removed, check that both wiper pivots move freely and without resistance. You can do this by grabbing the linkage and moving it back and forth.

Next remove the four 10mm wiper motor fasteners (green arrows).
Figure 22

Next remove the four 10mm wiper motor fasteners (green arrows). Then separate the wiper motor from the wiper assembly. Install the new wiper motor on the linkage assembly. Then use channel lock pliers to snap the ball socket onto the ball joint. Be sure this engages properly. You don't want to find out later it wasn't securely installed when you reassemble everything.

Then install the assembly into the vehicle.
Figure 23

Then install the assembly into the vehicle. Install all the fasteners finger tight in the reverse order of removal (see previous numbered photo). Then tighten. This ensures proper assembly and alignment. Connect the battery and turn the wipers ON then OFF. This will PARK the wipers. Next, install the cowl support and trim. Install the wiper arms. The right side arm is a standard install. Align your marks and then install the nuts. Remember the far right pivot has a slotted mount. The left side is a bit tricky. Place the shoe (red arrow) into the wiper arm (green arrow). Then install them together onto the pivot (yellow arrow), aligning your marks. Install the trim caps. Then reassemble the remaining items in the reverse order of removal. Once complete, check the wiper operation. If the wiper arms are chattering or not wiping well, see our tech article on wiper blade replacing and adjusting.
