Dimming
Replacement Bulbs:
The dimming of the interior lamps is done through the dimmer switch, located on the left lower corner of the instrument panel. The dimmer switch is fed 12 volts from the BCM through CKT 230. Current flows through the variable resistor of the dimmer switch, and back to the BCM through CKT 719. The BCM receives this signal and controls the intensity of the interior lamps. The lamps affected are for the I/P switch, HVAC control head, I/P cluster, radio, and transaxle range switch.
The headlamp switch must be in the PARK or Headlamp position in order for the interior lamps dimming feature to operate.
