Hey guys, new poster, no luck finding answer online. Recently my left rear blinker went out. Not the bulb itself as it was lit when I went to change it, changed anyway and still nothing. Replaced fuses. Still didn't fix. At this point its either bad relay that needs changing or probably wiring. I'm trying to access the turn signal relay so I can replace it but I'm having no luck finding where it is exactly. My vehicle is a 2003 Sonoma ZRX. If anyone could help me I would greatly appreciate it, thanks.

Does this help any?

Not really, I already changed out those two fuses and it didn't correct the problem. I was talking more about those bigger plug-like things that are supposedly hidden somewhere inside the dashboard (or underneath the dash or wherever). Thanks though!

The blinker module? Not sure exactly where that is located on your truck. But generally they are located right near the fuse panel. Mine is under it, or above it depending on how you look at it.

If your front blinker bulb is bad it will cause this issue..It just stays lit and doesnt blink correct

Its not the front, its the rear driver side thats not working. The bulb itself is lit, I've replaced the bulb and the issue was not resolved.

He'* saying the front bulb will effect the rear as well.

Do your flashers work?

your flasher relay should be located behind the glove box..its a square relay..

i picked up the one for our 99 s10 for about 15 bucks..you do have to remove the glove box to get to it..but i bet thats your culprit

i had the exact same problem on our s10 left rear wouldnt blink for the life of me..replaced that relay and BAMB she works!...it that was about 2 years ago IIRC

Thanks WAKEFIEDL, found the flasher behind the glove box! Its definitely a bit different than what I've seen online though. Its a single block (not metal can) that says both Turn/Hazard Flasher. And DRIVER97, I switched out the front blinker light too, it didn't fix anything other than I found a big fried drgaonfly under the hood of my truck, haha
