    Default 2006 Silverado brake light issue

    I have a 2006 Chevy Silverado. My question is regarding the brake lights.. My running lights are working fine, and the third brake light works properly as when I step on the brake it lights up, but my taillights do not. The turn signals work fine on both sides, and the bulbs look okay.. I am looking for something that may be the cause of this problem? Any help would be greatly appreciated.

    Go ahead and throw some new bulbs in. My 07 Classic ( 06 leftover) pops brake light bulbs every 6-8 mths. I just replace them both at once, saves time and tickets.

    You can also chase your wires from the firewall box back to see if there is any breaks or frayed wires.

    Thanks for such a quick reply! I'm definitely not against just getting new bulbs, but would they both go out at the exact same time?

    Heres how I see things, the truck is an 06, so its 6 years old, may have orginal bulbs. Bulbs and chasing wires are a cheap/free fixes before you go spending money throwing part guesses at it. Start Simple and work up.

    I agree. Try the bulbs first. I had my brake lights go out and came to find out some water had gotten in and started causing some corrosion in there. Fortunately I caught it early enough before it got bad. Always start simple though. And bulbs are cheap. Don't go get the best bulbs you can. Buy some cheap ones and try it out.

    There is a fuse for the stop lights in the instrument panel fuse box. It is a 15 amp fuse marked "VEH STOP" thereis also a fuse in the same box for the center high mount stop light (CHMSL) which is 10 amp. I would check this out.

    I got new bulbs and that wasn't it, so I got to looking at the fuses and found one that had blown. They now work. Thanks for your help.

    Vehicle info helps.

    You need to check for voltage at the tail light circuit board.

    No voltage, check the wiring, moving forward. If the wiring looks good, check for voltage at the brake light switch.
