Pulse Wiper - Phantom Wipe

Number: 84-212

Section: 10 (I)

Date: Oct., 1984
Subject: PULSE WIPER PHANTOM WIPE


Model and Year: 1984 CAVALIER
TO: ALL CHEVROLET DEALERS


CONDITION

Some 1984 Cavalier models equipped with pulse wipers (CD4 option) may experience a false (phantom) wipe when the turn signals are operated. This will happen with the wiper control in the "OFF" position.


CAUSE

The false wipe is caused by oxidation of the wiper switch contacts, which results in a high resistance condition.


CORRECTION

To repair this condition, install a new pulse wiper switch, P/N 7848195 for a standard column or P/N 7848196 for a tilt column. DO NOT use the old switches with P/N 7843025 or P/N 7844427. The new wiper switches have silver contacts to prevent oxidation and maintain continuity in the closed position.
