help, just bought a 2002 yukon denali xl, the 6 -gauge back lights dont work. all other dash lights do, all other vehicle lights do. all fuses are good, the 6 bulbs are new. light switch with dimmer control replaced but old seemed good. BCM doesnt seem to be getting a signal telling it to send power to the these lights. If the ambiant light sensor is bad could it keep the switch signal from getting to the BCM? does anyone know if there is a hidden relay from the switchand/or the ambiant light sensor that could be bad that me and my mechanic are missing, could the ambiant light sensor be the problem or something else? thanks

Anyone??

sorry wrong thread
