The windshield wiper motor in 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 central control module. The motor drives a pivot that moves the wiper arms to clear the rear window.

This article will cover replacing the rear window (tailgate) wiper arm and motor on Volvo V70 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.
