How to Change the Rear Windshield Wiper Motor on a 1999 Venture

The Chevrolet Venture minivan was introduced in 1997. The 1999 Chevrolet Venture was equipped with a 3.4-liter V-6 engine, which produced 185 horsepower. The 1999 Venture was available in three different trim packages: the base, LS and LT models. The rear wiper arm is connected to the wiper motor from the outside of the vehicle. All other removal and replacement procedures are done from the inside of the rear hatch. Replacement of the rear wiper motor should be performed by someone with prior mechanical experience.

Instructions

    1

    Trace a line beneath the rear wiper to ensure proper alignment during installation, using a window marker or white crayon. Remove the rear wiper arm nut from the back hatch, using a large open-end wrench or locking pliers. Pull the rear wiper arm horizontally out of the rear hatch.

    2

    Open the rear hatch on the Venture. Remove the fasteners from the inner hatch panel, using a Phillips screwdriver. Remove the inner hatch panel from the rear hatch.

    3

    Remove the electrical connector from the rear wiper motor, by hand. Remove the wiper motor mounting bolts, using a 3/8-inch drive ratchet and socket with a 6-inch or longer extension. Keep your hands free from the exposed door hatch frame as much as possible.

    4

    Pull the rear wiper motor out of the rear hatch. Install the new wiper motor and tighten the mounting bolts between 25 and 30 foot-pounds of torque, using a torque wrench and socket. Install the electrical connector onto the new wiper motor.

    5

    Install the rear hatch panel and tighten the fasteners until they are snug. Do not apply torque to the fasteners, as this can crack the hatch panel. Shut the rear hatch.

    6

    Install the wiper arm into the same position it occupied prior to coming off the Venture. Use your traced line beneath the wiper blade as a guide. Tighten the wiper arm nut onto the threaded stem with a large open-end wrench or locking pliers, until the nut is snug. Turn the nut 3/4-turn farther to acquire the 25 to 30 foot-pounds of torque necessary to hold the nut in place.
