ĭo you tow a trailer ? Check the trailer connector for corrosion ! Remove both LT an RT TRLR fuse's both 10 amp from the I/P fuse block an see if the problem goes away. Do you have a connection for a trailer hook up ? From looking at a wiring diagram B+ voltage from the STOP LP fuse 25amp in the under hood fuse box supply's the brake light switch, from there it feeds B+ to VEH STOP fuse 15amp and VEH CHMSL fuse 10amp an to stop lamp switch signal to the turn signal flasher module which is suppose to control the trailer stop lights. I think The turn signal/hazard module has something to do with the lights flashing. The voltage from the STOP 15-amp fuse is to the stop lamps, throttle actuator control (TAC) module, and the cruise control.

The voltage from the CHMSL 10-amp fuse is to the CHMSL and the trailer jumper harness. The turn signal/hazard module then supplies voltage to both of the trailer rear turn/stop lamp supply voltage circuits.
Fuse ext2 sierra driver#
When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both the STOP 15-amp fuse and the center high mounted stop lamp (CHMSL) 10-amp fuse in the instrument panel (I/P) fuse block, and to the turn signal/hazard module. The STOP LP 25-amp fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch.
