Wiper/defogger switch panel:




During the 1985 model year three different designs of wiper/defogger switch panels were used on the Buick Somerset. The first design (Figure 1) incorporated wiper "on" indicator lamps. Design II (Figure 2) remained cosmetically identical to Design I except that the wiper "on" indicator lamp bulbs were removed from the panel. Design III switch panels (Figure 2) contain no provision for indicator lamps.

The rear defogger switch indicator lamp was unaffected by these changes.

If a new wiper/defogger switch panel is ordered from the Parts Department, any one of the three design switches could be received.
