2008 Chevy colorado turn sig

That is chevy for ya. Should have bought a Ford.





heheh.

Need to see a diagram. Some late GM's have relays one for each side along with a fuse for each side. Since it does not work with the signal and the 4-ways. Just looked and there is a fuse for each side. Start there.

Unfortunately some of those modules have to be dealer programed- proprietary software that is not released to general shops.
Fords are like that as well.

Here's a diagram of the turn signal/ hazard light circuit. Most likely the BCM took a crap on you, but can't be sure till you check voltage, ground, and continuity of particular circuits. Hope this helps a little..

Must be low on blinker fluid. There is a sale going on at NAPA.




if not bulb or fuse then it looks like some digging around as others have said

Thanks for the help guys. Im 99% sure its the bcm. Last thing to check is if there is a short in the wiring. I'm not paying $400 for a F'ing turn signal. I'll stick my arm out the window, it's free.
