The headlight wiper motor is a permanent magnet electric motor that runs the headlight wipers via direct connection to the wiper blade. The motor speed is not variable. The wipers turn on along with the headlight wipers / washer function, located at position five on the wiper stalk.

This article will cover replacing the headlight wiper motor on Volvo V70 models. The wiper motor can be replaced in a few hours with minor disassembly of the headlight and radiator fan shroud. The wiper motor itself can fail, creating a situation where the wipers do not work or do not properly park. If you have a situation where washer fluid is leaking from the headlight wiper arm, replace the check valve located below the right front headlight.

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.

This photo shows a broken wiper arm.
Figure 1

This photo shows a broken wiper arm. I find a lot of these either stalled in the midway position or broken from being forced back to the park position. If broken, replace the wiper arm and motor.

Working at the wiper arm pivot, remove the plastic cap by opening it up.
Figure 2

Working at the wiper arm pivot, remove the plastic cap by opening it up. Then remove the 10mm fastener (red arrow).

Once the nut is removed, wiggle the wiper arm back and forth gently and lift (red arrow).
Figure 3

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

Lift the arm up and remove the washer hose (red arrow).

Lift the arm up and remove the washer hose (red arrow).

This photo shows the washer check valve (red arrow), shown with the right side headlight removed.
Figure 5

This photo shows the washer check valve (red arrow), shown with the right side headlight removed. To replace it, remove the right side headlight, detach the hoses and replace with a new one.

To replace a headlight wiper motor, remove the headlight on the side you need to replace the motor.
Figure 6

To replace a headlight wiper motor, remove the headlight on the side you need to replace the motor. Then remove the two 10mm wiper motor fasteners (red arrows).

To gain access to the cable that runs from the left to right latch, the fan relay mount (red arrow) has to be removed.
Figure 7

To gain access to the cable that runs from the left to right latch, the fan relay mount (red arrow) has to be removed. Start by removing the two T25 Torx fasteners (green arrows).

Then lift the relay mount up and lay it aside.
Figure 8

Then lift the relay mount up and lay it aside. You can leave the relays attached to it.

Pull the fresh air duct (red arrow) out of the radiator support and remove it from the intake air housing.
Figure 9

Pull the fresh air duct (red arrow) out of the radiator support and remove it from the intake air housing. Lay it aside.

Pull the fresh air duct inlet (red arrow) out of the radiator support.
Figure 10

Pull the fresh air duct inlet (red arrow) out of the radiator support. Pull it straight up to detach the rubber mounts. When reinstalling, be sure the rubber mounts (yellow arrows) are properly seated in the slots (green arrows).

Push the radiator away from the radiator support enough so the wiper motor (red arrow) clears the side of the radiator (green arrow).
Figure 11

Push the radiator away from the radiator support enough so the wiper motor (red arrow) clears the side of the radiator (green arrow).

Remove the wiper motor from the radiator support (red arrow).
Figure 12

Remove the wiper motor from the radiator support (red arrow). Disconnect the electrical connector (green arrow) by pressing the wire release tab and pulling it apart.

The steps above highlighted the left side motor.
Figure 13

The steps above highlighted the left side motor. The right side motor is a bit harder to get out. The E-box harness conduit (red arrows) blocks removal. If you have to replace the right side, I suggest either removing the E-box conduit or the radiator, to make life easier. When installing, install the motors and headlights. Connect the battery and turn the wipers wash function ON then OFF. This will PARK the wipers. Next install the wiper arms. Then reassemble the remaining items in the reverse order of removal. Once complete, check the wiper operation.
