Fog Lights Circuit Description Oldsmobile

When the park lamps are on, battery positive voltage (B+) is applied through the instrument panel (IP) fuse block INT LPS fuse via CKT 32 (YEL) to the fog lamp switch. Battery positive voltage (B+) is applied at all times through the IP fuse block FOG LAMPS fuse via CKT 1840 (ORN) to the switch side of the fog lamp enable relay position C. When the fog lamp switch is placed in the ON position, battery positive voltage (B+) is applied to the coil of the fog lamp enable relay position C. The coil receives ground through the lamp control module (LCM). With the fog lamp enable relay position C coil energized, the contacts close. This applies battery positive voltage (B+) to the fog lights. If the high beam headlamps are turned on, the LCM removes ground from the lamp enable relay position C and the fog lights turn off.
