Question about 2003 GMC Sierra
I have just installed a factory gmc fog light kit for a 2003 sierra. It came with all items needed, ie. wire harness, relay, lights, etc. I followed all directions and double checked all connections. I have a good ground. The fog light switch in the cab stays lite all the time and the fog lights will not work. I heard the relay click when I was hooking up the ground wire. Was it supposed to do that? Why will they not work. I know that the headlamps need to be on. The cargo light works though. Thanks
Sounds good to me except, the switch light shout be on the relay primary circiut and light off until you turn it on. When you turn the switch on, it lights up and energizes the relay, the relay closes and completes the secondary circiut for ythe fog lights. VIOLA' I have a silverado. done deal thanks
