Windshield Wiper System Information
|
Second Generation Camaro Owners Group Windshield Wiper System Information |
Concealed wipers became the standard wiper system in 1979 with delayed (or pulse) wipers being optional.
3 different motors were used. The Standard motor, which is rectangular in shape, or 2 versions of motors for concealed wiper systems. A non-pulse (off, on/low, or high speed) or A Pulse wiper (delay). The concealed motor can be identified by it having a round cylinder hanging sideways from the motor.
The non-pulse motor runs from late 73 to 1981 and has an integrated magnet switch and terminal board.
The pulse system started in 1977, and ironically is the same motor as the 1970 - early 73 motor. It uses a separate magnet switch and terminal board.
