If my break light wont work and I replaced bulb, what could the problem be and/or where should I troubleshoot next?
it's a 03 Cadillac CTS. I could have sworn when replaced bulb the break light was working but tail light wasn't. It got dark so I stopped trying to fix and I'm unsure since it was week ago but now it's the taillight working but no break light. it's the bulb that does both. it gets brighter when break applied only this bulb (brand new) wont get brighter thus break light comes on. I don't want to replace entire fixture so I want to be sure I check all other/cheaper problem areas. pleas help.
