Hi,
I have a light problem with my GC2003. Head light turn on normally but no back light .. even in the plate support. Others ext light works perfecty (brake light, flasher, ....).
I check all the fuses (hood) .. seems ok ..
Any ideass ???..
It should be a fuse or relay problem .. but which one and where it is ?
Thanks for your help ..

 

have some one check out the drivers from the bcm to the backup light ckt in the back. Ohm the wires from the bcm to the tail lamps if they are good then u have a bcm issue and they cost some money.
