I recently purchases a Covermaster Topper for a 2004 1500. I tried wiring the 3rd brake light and have it all hooked up correctly to the CHMSL wire and ground. I tested a different light and it worked fine, but the brake light won't turn on. I connected a multimeter to the brake light and no reading showed. All the wiring looks good in and out of the light. I would be shocked if the LED bulb set is burned out but I don't know any other reason why it won't turn on. Any suggestions?? Or what is the best way to change out a topper brake light??
Thanks for any help.
