⚠️ WARNING: Always disconnect battery before working on any electrical component.
Turn off ignition and all accessories.
Disconnect the negative terminal of the 24V battery to prevent short circuits.
Remove windshield cowl cover/grille (located at base of windshield).
Clear leaves, dirt, and debris from the area.
Disconnect wiper arms from linkage (mark positions if reusing).
Unplug multi-pin connector from the motor.
Inspect for corrosion, bent pins, or moisture damage.
Loosen and remove mounting bolts (usually M6 or M8).
Detach linkage rod(s) from motor crank arm (use puller if stuck).
Carefully extract the old motor from its housing.
Attach new motor securely using original brackets.
Reconnect the linkage rod to the output crank — ensure proper alignment and secure locking clip.
Torque mounting bolts to manufacturer specification (~10–15 N·m).
Plug in electrical connector firmly.
Reinstall cowl cover and wiper arms.
Reconnect battery.
Turn on wiper switch and test:
Low speed
High speed
Intermittent mode
Auto-stop/park function
✅ Confirm no binding, noise, or misalignment during operation.
