Before going into panic mode, the problem can be caused by a defective bulb. It is not that common, but it does happen on occasion when a bulb shorts internally and blows the fuses. Many times vehicles are disassembled, wiring harnesses opened up for inspection or replaced only to have the same problem after repairs, when the problem was a bulb. Check and / or replace all of your tail lamp and front parking lamp bulbs. Look at the sockets for corroded, overheated, melted connectors and replace if needed. Also inspect the contacts on the taillamp housing, they too can overheat, melt etc. As a last resort, CAREFULLY inspect the wirning harnesses from each lamp, looking for pinched, chafed, cut harnesses and wires. Also look for puncture holes from screws etc.

Automatic headlamps are controlled by the Cab Compartment Node (CCN). The CCN is your instrument cluster . With the headlamp switch in the AUTO position, the CCN will control the headlamp, parking, side marker, tail and instrumentation lamps based on ambient light levels. Ambient light levels are monitored by the CCN using the ambient light signal present. Ambient light readings are averaged to limit cycling the lamps ON and OFF when passing through areas with varying light levels. The automatic headlamps will only function when the engine is running with the RPM greater than 300. When the headlamp switch is in the AUTO position (Automatic mode), the Headlamp Time Delay system will function when the ignition switch is placed in any position other than run/start.

The following functions are controlled by the FCM:
Air conditioning condenser cooling fan
Daytime running lamps - if equipped
Fog Lamps
Front and rear hazard warning lamps
Front turn signals
Radiator fans
Rear window defroster power and timing
Stop, turn signal and tail lamps
Windshield and liftgate wiper and washer systems
