No stop light in BUMPER One side ONLY??

STOP LAMPS
The STOP LP 25 A fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses
the brake pedal, the switch contacts close and battery positive voltage is supplied to both the STOP 15 A fuse and the CHMSL 10 A fuse in the IP fuse
block, and to the turn signal switch. The turn signal/hazard module then supplies voltage to both of the trailer rear turn/stop lamp supply voltage
circuits. The voltage from the CHMSL 10 A fuse is to the center high mounted stop lamp (CHMSL) and the trailer jumper harness. The voltage from
the STOP 15 A fuse is to the stop lamps, throttle actuator control (TAC) module, and the electronic brake control module (EBCM). The CHMSL is
grounded at G410. The stop lamps are grounded at G401.

PARK, TAIL AND MARKER LAMPS
The park, tail, and marker lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position, or
anytime the headlamps are requested. The underhood fuse block supplies battery positive voltage to both the park lamp relay switch contacts and the
park lamp coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are
turned on the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the FR PRK 10 A fuse, RR PRK 10 A fuse, LR PRK 10
A fuse, and the TRL PRK 10 A fuse, and to their respective park and marker lamps. The front park and marker lamps are grounded at G100. The rear
park and marker lamps are grounded at G401. The license lamps are grounded at G410. If the headlamp switch is left in the ON position, the
inadvertent power control feature will turn off the park, tail, and marker lamps, approximately 10 minutes after the ignition switch is turned to the OFF
position. If the driver places the headlamp switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the
ACCY position, the park, tail and marker lamps will remain on until turned off or the battery runs dead.

MUD & Others,

Thanks for all of your help. Turns out it was the flasher relay. Replaced it under the dash and everything is operating normal now.

Thanks again guys!!
