Hello Monte Carlo Forum, how's everyone doin? Ok, so here's the problem, my girlfriend has a 7th Gen. 2006 Monte Carlo SS ,*[

 

Most likely if you replace all the bulbs on that side they will work again. With most of the courtesy lights if one goes haywire the rest will not work properly as a warning to check them an do a repair. Signal lights will just stay on if one is bad, so now you will need to find the bad one and replace it. Don't always purchase the cheapest one as they may only last a short time and you have the same issue. Hope that helps some otherwise you will need to provide more info.

 

Just need to change the bulb. There's 2 filaments in the brake/ blinker bulbs. It will still light up when the headlamps are on but won't brighten when brakes applied or signal on.

 

Sorry everyone...never finished typing out my problem and didnt know it had actually posted. Thanks for tryin to help. I know which one is "bad" but the coil in the bulb looked to still be connected and not blown, so i was just curious whether it would possibly be a common wiring issue or something since the taillights work and just the brake/turn signal. Thank you for takin the timeto try and help
