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 are 2 dimmer module that supply current to the panel lights. The right dimmer module supplies current via CKT 8 (GRY) to the following components:
^ The seat switches
^ The seat/lock switches
^ The power window switches
^ The passenger temperature control
^ The ashtray lamp
^ The shift select switch lamp
^ The power mirror switch
^ The fog lamp switch
^ The release switch
^ The traction control switch
The left dimmer module supplies current via CKT 1244 (BRN) to the following components:
^ The steering wheel controls
^ The instrument cluster
^ The heater and A/C control
^ The radio
