Having problems with your 2003 Chevrolet Silverado 2500HD ?
I have checked all fuses and they are good. The brake light on the cab works. All of the tail lamps are good. Every other function works. It has a trailer hookup also. All of the plugin connections have been checked. I checked the brake light switch and it is working.
Check for power at the actual bulb socket for brake applied and also check for ground . If not check for a boken or damaged wire check connection at trailer as well for P and G. may not be recieving input from brake light switch
