Question about 2005 Chevrolet Suburban
You bcm (body control module is bad) to have the dealer replace it will run you about $400. a quick fix for the reverse light is to splice 2 wires into the wire for the center plug in your trailer wiring. now run a wire up to each reverse light, cut the green wire to each reverse light and **** conect them up. this is a seperate revers feed than the one from the bcm. the dome lights remove the light cover on the second set of interior lights (the one between the drivers seats). the two side bulbs are map lights the center bulb is for the dome lights. run a jumper wire from the right or leftside socket to the center socket. you dome lights will now turn on with just the use of that switch i replaced the back bulbs with led's soo there is no extra amp's being drawn. you could bypass the bcm but i could not find any wiring diagrams for it and i dont know if it can take the added amp's

You can't turn them on manually ?
This could be a BCM problem , this best left to a ASE certified repair shop or the dealer .
