Your 1988 Chevy S10 could have come equipped with a four-cylinder engine or one of two six-cylinder engines. The front wiper motor on your S10 rotates a slightly bent arm that leads to the rotation of your wiper arms. Your wiper motor has likely lasted most of the life of the truck, but like all components will eventually need replaced. Regardless of the engine and transmission setup, replacing the front wiper motor is the same.
Instructions
- 1
Place a line of tape along the edge of each wiper place to use as an alignment aid later. Pry upward on the rubber caps that protect the arm attaching nuts. Remove the arm retaining nuts. Carefully lift the wiper arm off of the windshield and linkage.
2Pry upward around the edges of the cowl vent with a pry bar to release the clips. Place the cowl vent aside. Loosen the bolts for the passenger and driver wiper linkages, but do not remove them. Slide the linkages off of the wiper motor. Disconnect the wiper motor electrical connector. Remove the three 10 mm bolts from the wiper motor and place them aside. Pull the wiper motor away from the firewall.
3Position the new wiper motor in place and install the wiper motor bolts. Tighten the bolts to 71 inch-pounds with a torque wrench. Slide the wiper arm linkages over the wiper arm shaft and tighten the mounting bolts; the driver side goes on first.
4Tap the cowl panel into place and connect the wiper motor electrical connector. Line up the wiper blades with the tape mark on the windshield and slide the arm onto the wiper linkage. Install the mounting bolts and tighten snug. Remove the tape lines. Turn on the wipers and verify proper operation.
