Today’s Zip Corvette technical question comes from Aris who owns a 1969 Corvette.

How do I remove my Corvette’s windshield wiper motor?

Answer: The wiper motor is held to the cowl by three studs coming from the windshield side. First, gain access by raising the wiper door assembly to its highest position, this can be done by removing the plug from the wiper door vacuum canister and pulling the wiper door up. Additional access can

be gained by removing the (8) screws holding the wiper door grill in place. Disconnect the wiper arms from the ball stud on the back of the wiper motor; two nuts with attaching washers hold the arms to the ball stud. There is also a single nut that holds the ball stud bracket to the back of the wiper motor, this may need to be removed as well. Try to reach these components without removing the wiper door, as removing wiper doors typically cause other problems including broken bolts which typically require professional repair. Once the arms are loose, simply loosen the three nuts on the front of the wiper motor and the motor can be pulled straight forward and off the cowl. When replacing the wiper motor with a new or rebuilt unit, order separately the wiper motor mount bushings as these are usually dry and cracked due to engine compartment heat.

Today’s Zip Corvette technical question comes from a C3 Corvette owner:

How do I adjust the windshield wipers on my 1976 Corvette?

Answer: The wiper arms fit into a specific groove on the wiper arm transmissions coming through the top of the cowl, therefore no adjustment exists on the exterior of your 1968-1982 Corvette. The

Wiper Arm Adjustment

adjustments for your wiper arm locations are found on the backside of the Corvettes wiper motor where the link arms attach to the wiper motor ball stud. This can easily be found on 1973-1982 Corvettes where access is granted, but on 1968-1972 Corvettes the wiper door may need to be removed or lifted in the very highest position. Once the nuts are loosened, the wiper link arms will “slide” to allow for proper adjustment. The nuts can be tightened once the arm locations are adjusted enough to make sure the wiper blades do not hit when returning to their inside position.
