1968-82 Corvette Wiper System Exploded Diagram - Motor, Arms & Linkage

This document is an exploded parts diagram of the windshield wiper system for 1968–1982 model years, titled "68-82 Wiper System." It was uploaded to the gallery of a 1977 Chevrolet Corvette, which falls within the stated year range. The line-art illustration shows the complete wiper assembly as installed at the base of the windshield/cowl area, with individual components pulled apart to show their relationships. Six components are labeled with callouts: the wiper arm head with blade (upper left, showing the arm-and-blade assembly), the wiper arm vacuum valve (with its mounting hardware, screws, and plate shown exploded), the transmission link assembly (the long linkage connecting the pivots across the cowl), the wiper arm (right side), the wiper motor (lower left, with mounting bolts shown), and the firewall seal (the round grommet/seal where the linkage or motor shaft passes through the firewall). A reader can learn the names of the major wiper system components, how the motor drives the transmission link assembly to move both wiper arm pivots, and where the firewall seal and vacuum valve fit in the assembly. No part numbers, torque specifications, or written instructions are included—identification is by visual callout only.
