I just purchased a 2003 gmc envoy. today i was going through and replacing lights. the last light i had was a license plate light. i put it in but went on and off. took the light out and could see that the connector was a little corroded. i took a pick i have to clean it up but totally forgot to turn the switch off. i seen it spark and now the license plate lights don't work and the drivers side tail light doesn't light up. when i press the brakes all three work and so do the turn signals. i swapped the two tail light assemblies, but the problem is still with the drivers tail light. i checked all fuses, all good. did i mess up the light switch? did i mess up the body control module? please help.
