The headlamp switch receives voltage from the central junction box (CJB) fuse 7 (30A) through circuit 196 (DB/OG). When the headlamp switch is placed in the HEADLAMPS ON position, voltage is routed to the multifunction switch through circuit 15 (RD/YE). The multifunction switch then routes the voltage to the headlamps through the CJB.
Possible Causes
- Fuse
