Hello. I have the car listed above GT model. The lower dash board lights, shift console and tailgate lights do not come on. I replaced the fuse and rely switch and lights still do not come on. Can you tell what is wrong and how to fix it?

Would the BCM connection or BPPF having gone bad cause this with the tail lamps, lower dash lights, console shifter and door locks not coming on?
Again back up lights come on and brake lights.

The BCM controls these circuits. I have included the wiring diagrams so you can see how the system works with the instructions on how to replace the BCM in the diagrams below. Check out the diagrams (below). Please let us know what happens.

I took the car to a GM dealer they checked the BCM and said not is not the problem. Wanted $139.00 to do a diagnostic then cost to fix. Any other idea what could be wrong I can check and see if I can fix it? Thank you.

Looking at the wiring diagrams I see an interior light fuse. Can you check to see if it has power please?

It is late just seeing the message I will check in the morning. Thank you and this would affect the tailgate lights as well? Will have to check the diagrams as to whether the fuse is in the side fuse box inside right side of car or under the hood. Thank you.
