Pulse Wiper - Phantom Wipe
Bulletin 84-8-16Date Oct.. '84
Ref. No. 85-031-8
SUBJECT: PULSE WIPER PHANTOM WIPE
MODELS AFFECTED: 1984 SKYHAWK
CONDITION
Some 1984 Skyhawks 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 usually 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, part no. 7848195 for a standard column or part no. 7848196 for a tilt column. DO NOT use the old switches with part no. 7843025 or part no. 7844427. The new wiper switches have silver contacts to prevent oxidation and maintain continuity in the closed position.
If the new switch does not correct the phantom wipe condition, check for a loose or corroded connection, pinched wire or open circuit.
