Turn Signal not working

[Sugarray_11]

I got an 09 Sierra SLT and just realized my front drivers side turn signal don't work. I replaced all the bulbs and everything is working but those 2 amber turn signal lights dont work. The parking light on the same bulb works. The same side in the back work. It's just the 2 that don't blink. What do you all think? New to the forum. Thanks!

Check the underhood fuse box first (I forget if they're there, or in the cab - easy enough to check both anyway).

 

Could've blown when the old bulb failed.

I checked both out and they look fine. Thing is the parking lights still work and in the same.side the blinkers flash except for the 2 amber ones in the front.

Parking lamps are a totally different circuit. Completely unrelated to the t/s, except that they share the same bulb.

 

I'd grab a test light and see what has power, and what doesn't. I can assume the ground is good since the parking lights work. Do a visual inspection of the wiring first - the problem could be an obvious one.

 

Also make sure that bulb is in correctly - there are 2 different height pins on the side - they can only go one way in order for everything to work normally.

 

EDIT ... since you have an '09, they're probably flat, so scratch that.

Thanks. I'll give it a shot. And yes it's flat bulb ends.
