Inside turn indicator blinks normal for 2 durations then starts going faster. Front Lights and turn signals work, but Driver Side REAR turn signal, Night Lights and Brake lights are inoperative. Unsure about Reverse... I replaced bulbs in both Turn and Night lights. Pretty sure that its a Wiring or ground issue, but don't even know where to get replacement wires other than paying the dealership to fix it.
Turn Signal Lamps
The LT T/SIG and RT T/SIG fuses located in the underhood fuse block supplies battery positive voltage to the body control module (BCM) for turn signal and hazard lamp operation. When the turn signal switch is place in either the LEFT or RIGHT position, ground from G202 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. The BCM also sends a message via GMLAN to the instrument panel cluster (IPC) to cycle the turn signal indicator ON and OFF depending on the position of the turn signal switch.
Ground for the turn signal lamps is supplied as follows:
• G101 provides ground for the left front turn signal lamp
• G100 provides ground for the right front turn signal lamp
• G302 provides ground for the left and right rear turn signal lamps
The LT T/SIG and RT T/SIG fuses located in the underhood fuse block are also used by the body control module (BCM) for stop lamp operation.
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The body control module (BCM) provides both, a 5-volt reference voltage and low reference to the brake pedal position sensor. The position sensor provides an analog voltage signal back to the BCM that will increase as the brake pedal is applied. When the brake pedal is applied, the BCM will then apply battery voltage to the left and right stop lamp supply voltage circuits and the center high mounted stop lamp (CHMSL) supply voltage circuit illuminating the stop lamps. At the same time the BCM signals the transmission control module (TCM) and the engine control module (ECM) that the brakes are applied. Ground for all stop lamps is provided at G302.
The stop lamps on this vehicle will not illuminate unless the ignition is in the accessory, run, or crank positions. When the ignition is in the OFF position the stop lamps will not illuminate when the brake pedal is applied.
Did you check the fuse's. ? Wouldn't think it's a ground because right an left tail lamp Assembly's use same ground ! Did you check for B+ voltage at the bulb. with a volt meter ? Power is supplied by the BCM . Could be the tail lamp assembly

sounds like the bulb you have is the wrong resistance the new noen bulbs will do this
SOURCE: front driver side turn signal light doesn't flash
replace flasher......usually located in fuse block area...listen in this area....select passenger side ...then select driver side...you can hear flasher clicking...you have seperate flashers for each...FLASHERS are small cubes plugged into fuse block....probable bad driverside flasher

Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.
