No rear driving lights. All in front are OK, and brake lights, backup lights, and turn signals are OK in back. However, there are no standard driving lights functioning in the rear, including license plate light.

Bulbs are good - swapped with blinkers and work fine. Suspected fuse, but all fuses are in tact.

Any ideas?

Hi drericg, Welcome to 2carpros and TY for the donation

Check and test fuse no. 15 50amp in the integrated power module at left front of engine compartment. If okay test the park lamp relay or swap it with a like one if okay problem is coming from the front control module

I checked fuse 15 (50 amp) and it was good, but swapped anyway. No change. I also swapped relay with another identical. Again no change.

Can I test the FCM? How do I access?

Thanks

Thanks for the diagram! Sorry I don't understand "BRB with the EWD" from your previous post. Can you explain?

Is the FCM near the fuse box? How to access?

Thanks.

Disregard the FCM

Check these splices at S324/326-The S324 is at the left rear chassis and the 326 right rear chassis-See below

Note: both tail and license lights going to the back meets up at theses splices-the ground is good otherwise the brake/turn signals w/n work-they all share the same common ground-go ahead and check the G106 see below

I looked at splices and ground. All appears OK.

I checked voltages at plug into rear light panel on one side. 5 wires go in. It appears 2 are ground and 3 power to the 3 bulbs. Each gets power (and light up) at appropriate times: backup when in reverse, brake when brake on, blink with turn signal. "Lamp Out" light on dash lights up when lamp is pulled. However, nothing seems to be telling the appropriate lights to turn when when head lights are turned on, so back of truck is dark unless turning, signaling, or braking.

Any further ideas? Did I miss something?
Thanks

Hello if you are still looking for the FCM its on the side of the fuse box in the fender unbolt the whole fuse box and the FCM is the metal box that is screwed to the side of it. Trust me I got a truck here with no brake lights turn signals horn or windshield wipers. Hope I could help.
