2004 Trailblazer LT, 4.2 No Backup lights
Hello, I have a 2004 Trailblazer with no backup lights. I have ruled out the bulbs, the light assembly, checked the fuses, and I changed the Neutral Safety switch. I have been told that it could be the PCM or the BCM. Are they the most likely reason for this problem at this stage, after ruling the other things out?
