Step-by-Step Instructions

Follow these steps carefully

Buy 24 and 20 front blades, and measure the rear blade

The rear wiper is a 12-inch blade on a small hook arm — but measure it, because one catalog lists 11 inches while the original-equipment listings and most charts say 12.

Stop the blades mid-wipe with Rainsense off

First, make sure the Rainsense auto-wipe is switched off — the sensor sits near the top center of the windshield and you do not want it triggering a sweep mid-job.

🔧 Mechanic's note — Ray Delgado

I tug-test every blade after installing. A blade that isn't latched will fly off at highway speed, and that's terrifying.

Open the latch and release the driver's blade

Lift the driver's arm away from the glass until it holds upright, and lay your towel on the windshield beneath it. Open the small latch on the blade's center connector — the owner's procedure describes pulling the blade assembly down toward the windshield with the latch open — then push the release lever to disengage the arm's hook from the blade assembly and slide the old 24-inch blade free. The latch-and-lever motion feels different from a plain tab, so work it gently until you feel the release.

Latch the new 24-inch driver's blade on

Push the new 24-inch blade's connector onto the arm's J-hook until the release lever clicks into place, then close the latch. Tug it firmly to confirm the lock — a half-latched blade can slide off the hook at highway speed.

Swap the 20-inch passenger-side blade

Repeat the latch-and-lever procedure on the passenger side with the 20-inch blade. Confirm the lock with a firm tug and lower the arm gently back to the glass.

Replace the rear wiper using the accessory-mode procedure

Now the liftgate. The owner's procedure: put the vehicle in accessory mode and switch the rear wiper on — it will stop pointing downward — then switch the vehicle fully off and pull the wiper arm away from the rear glass. Release the small rear blade from its hook the same way as the fronts, fit the new 12-inch blade (the length you measured) until it clicks, and lower the arm back onto the glass with extra care. Start the engine afterward and the rear wiper will return to its normal parked position on its own.

Test everything and note the Rainsense and HUD glass quirks

With all three arms resting on glass, start the vehicle and run the washers front and rear through several cycles. You want silent, streak-free sweeps edge to edge, with the rear blade parking flat and not overrunning the glass. Two XT6-specific notes: the Rainsense sensor needs a clean patch of glass to read through, so make sure the glass in front of it is spotless; and if your windshield ever needs replacement, it must be the acoustic glass designed for the head-up display, or the HUD image will look out of focus. Replace wiper blades about once a year.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Leaving the Rainsense auto-wipe armed while you work — a splash on the sensor near the top of the windshield can trigger a sweep with your fingers at the connector.
• Forcing the short rear arm upward like a front arm. The rear arm is stubby and springy; lift it just enough to work and keep a firm grip the whole time.
• Buying an 11-inch rear blade because one catalog lists it, when your car wears the 12-inch blade that most charts (and the original-equipment listings) specify. Measure the old rear blade first.

Tools You'll Need

Tape measure or ruler (to settle the 11-vs-12-inch rear-blade question) Soft cloth or folded towel (to cushion the glass under a bare arm) Glass cleaner and paper towels (to clean the windshield, especially the Rainsense sensor area)

⚠️ Safety First!

• Never let a bare wiper arm snap back onto the windshield or the liftgate glass — the spring-loaded arm can chip or crack the glass. Keep a folded towel under your work area.
• Work with the ignition fully off (except for the brief accessory-mode step for the rear wiper) and the Rainsense system disarmed.
