    • Raise the hood.

    • Remove the negative terminal clamp from the battery. Should be 10 mm

    • Apply painters tape to the windshield under each wiper arm.

    • Use a mark to record the wiper arm position on the windshield

    • Remove Antenna, use the proper wrench to loosen the antenna from the base.

    • Pull the washer hoses off of the small studs near the wiper arm bases.

    • Open the plastic caps from the base of the washer arms, using the proper socket wrench, loosen and remove the hold down nut.
