How Much Does It Cost To Replace A Rear Wiper Motor?

Total replacement cost for a rear wiper motor in 2026 runs $225–$320 when you combine parts and labor. Labor usually lands between $65–$85, while the motor itself runs $160–$235. These prices assume you're going with a fresh OEM unit or a solid aftermarket option, plus professional installation.

What’s going on here?

The rear wiper motor is basically a tiny electric motor that powers your single rear blade. Over time, the internal brushes, gears, or armature can wear down from heat, moisture, and all the grit your car kicks up. When it fails, you’ll usually notice the blade doesn’t move at all, only works on one speed, cuts in and out, or won’t return to its parked position. Since these motors are sealed and generally can’t be repaired, replacement is pretty much the only way to fix it.

Here’s how to actually fix it

1. Make sure the motor’s the problem. Flip the rear wiper switch to ON. If the blade doesn’t budge but you hear the motor buzzing, it’s probably toast. No sound at all? Check the fuse first.
2. Find the motor. On most 2020–2026 models, the rear wiper motor hides under the rear hatch or liftgate, accessible from inside the cargo area. You’ll need to pop off the interior trim panels—grab a trim tool kit for this.
3. Unplug the wiring harness. Squeeze the release tab gently and pull the 2-pin or 3-pin connector straight off. Don’t twist it, or you might bend the pins.
4. Take out the mounting bolts. Grab a 10 mm socket and remove the two or three bolts holding the motor to the hatch. Toss them in a magnetic tray so they don’t vanish under the car.
5. Disconnect the wiper linkage. Some setups use a ball joint, others an Allen-head link. Loosen the set screw or clip, then wiggle the link off the motor shaft.
6. Swap in the new motor. Line up the new motor’s splined shaft with the linkage and hand-tighten the mounting bolts. Plug the wiring harness back in until it clicks into place.
7. Put the trim back. Snap those panels back in, making sure every clip snaps into place. Test the rear wiper switch to confirm the blade parks where it should.

Still not working?

• Test the rear wiper relay. Pull the relay from the under-hood or interior fuse box (check page 247 of your 2026 owner’s manual). Swap it with a known-good relay—like the horn relay—and test again. A new relay runs $15–$25.
• Check the fuse and wiring. Find the rear wiper fuse (usually 10 A or 15 A) in the fuse block. Pull it and look for a broken filament. If the fuse looks fine, use a multimeter to check for 12 V at the motor connector with the switch ON. No voltage? Follow the wiring for any damage or corrosion.
• Replace the wiper linkage. If the motor spins but the blade stays put, the plastic linkage might be stripped. OEM linkages cost $30–$50 and bolt in with the same two screws.

Keep this from happening again

• Lube it up once a year. Hit the motor’s pivot arm and linkage joint with silicone grease annually to cut down on friction and keep moisture out.
• Clean the blade and glass. Every six months, wipe the blade and glass with a 50/50 mix of isopropyl alcohol and water to remove tree sap and road grime that can overwork the motor.
• Park in the shade when you can. Heat kills brushes fast. No garage? A simple windshield sunshade can make a big difference.
• Consider a heavy-duty motor. Some aftermarket motors—like Dorman or ACDelco—come with metal gears and sealed bearings, pushing their lifespan past 250,000 cycles. Honestly, this is the best way to avoid repeat repairs.
