Panel Dimming

When the park lamps are on, battery positive voltage (B+) is supplied through the instrument panel (IP) fuse block INT LPS fuse via CKT 32 (YEL) to the dimming switch. The dimming switch supplies a variably controlled voltage to the dimmer module(s). The potentiometer in the panel dimming control cannot provide enough current in order to operate the panel lamps. The dimmer module(s) amplifies the current, supplying the variable voltage to the panel lights. As the amount of the current increases, the lamps become brighter. As the amount of the current decreases, the lamps become dimmer.

There is only 1 dimmer module that supplies current to the panel lights. The left dimmer module supplies current via CKT 8 (GRY) to the following components:
^ The headlamp switch
^ The door switch flood lamps
^ The heater and A/C control
^ The door handle flood lamps
^ The passenger temperature control
^ The ashtray lamp
^ The shift select switch lamp
^ The instrument cluster
^ The steering wheel controls
^ The reset switch
^ The trip odometer
^ The radio
