The windshield wiper motor is 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 pivot that turn the wiper arms to clear the windshield. On MINI R56 models, the linkage runs one pivot to each wiper.

This article will cover replacing the windshield wiper motor and linkage on MINI R56 models. The wiper motor assembly 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 free 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.

MINI does not make the wiper motor available as a single part. It comes preinstalled to the transmission. That does not mean an aftermarket replacement option will not become available. Due to this possibility, I will show you how to remove the wiper motor assembly, then how to separate the motor from the transmission.

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.

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

The windshield wiper motor is a permanent magnet electric motor that runs the windshield wipers via a linkage (transmission).
Figure 1

The windshield wiper motor is a permanent magnet electric motor that runs the windshield wipers via a linkage (transmission). It is located beneath the wiper cowl (red arrow) and operates a transmission that moves the wiper arms (green arrows).

Working at the wiper cowl, peel off and remove the seal (red arrow).

Working at the wiper cowl, peel off and remove the seal (red arrow).

Move to the right side of the cowl, near the hood strut.
Figure 3

Move to the right side of the cowl, near the hood strut. Remove the two 10mm fasteners (green arrows).

Remove the battery trim panel cover from the cowl.
Figure 4

Remove the battery trim panel cover from the cowl. Lift it straight up to detach it from the windshield and remove it.

Working at the right and left side wiper arm pivots, remove both plastic caps (red arrow) by pulling them straight up.

Working at the right and left side wiper arm pivots, remove both plastic caps (red arrow) by pulling them straight up.

I like to mark the position of the wiper arms using a paint marker.
Figure 6

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. You can mark the pivot or the wiper location on the windshield (yellow arrows).

Once you have marked the arm, remove the 13mm pivot nut (red arrow).
Figure 7

Once you have marked the arm, remove the 13mm pivot nut (red arrow). Then remove the washer (yellow arrow). The left side is shown; the right side is similar.

Next, you have to remove the wiper arm.
Figure 8

Next, you have to remove the wiper arm. What I do is, I wiggle the wiper arm (red arrow) to remove it from the pivot shaft (yellow arrow). 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.

Move to the left side of the cowl, near the hood strut.

Remove the cowl trim panel cover (red arrow) from the cowl.
Figure 10

Remove the cowl trim panel cover (red arrow) from the cowl. Lift it straight up to detach it from the windshield and remove it. Once removed, you have access to the wiper motor assembly (yellow arrow).

Working at the wiper motor transmission, remove the 13mm center fastener (green arrow) and the two 10mm Torx fasteners (red arrows).
Figure 11

Working at the wiper motor transmission, remove the 13mm center fastener (green arrow) and the two 10mm Torx fasteners (red arrows).

This photo shows the 13mm fastener (red arrow), located beneath the wiper motor pivot (green arrow).

This photo shows the right side 10mm fastener (red arrow).
Figure 13

This photo shows the right side 10mm fastener (red arrow). The left side 10mm fastener is similar.

This photo shows the 13mm fastener bushing with washer (red arrows).
Figure 14

This photo shows the 13mm fastener bushing with washer (red arrows). The washer usually falls out and lands behind the brake booster. Pay attention when removing the motor assembly. Keep an eye out for the washer, as you don't want to lose it if you plan to reuse it.

Lift the wiper assembly up and slide it out of the cowl far enough to access the electrical connector.
Figure 15

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 (red arrow) and sliding it off (green arrow). Once the electrical connector is disconnected, remove the wiper motor assembly from the cowl.

MINI does not sell the wiper motor or assembly as separate parts.
Figure 16

MINI 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. I like to use a trim panel tool to lever it off the ball joint. 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 three T30 Torx wiper motor fasteners (red arrows).
Figure 17

Next, remove the three T30 Torx wiper motor fasteners (red arrows). Then separate the wiper motor from the wiper assembly. Install the new wiper motor on the linkage assembly.

Then use channel locks pliers to snap the ball socket onto the ball joint.
Figure 18

Then use channel locks 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. Install all fasteners finger tight in the reverse order of removal. 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, aligning your marks. Install the trim caps. Then reassemble the remaining items in the reverse order of removal. Once complete, check the wiper operation.
