I cannot figure out what the problem is. My left turn signal will not illuminate. I have change the bulb and checked wiring, but have yet to come across anything out of the ordinary? Maybe try ground? Yet I have not went too far in depth because it's a little wet outside right now...little late for all this snow in southern Illinois...

 

Has anyone experienced this?? Or something similar?

 

When you engage the left turn signal, what happens? Do you hear the flasher unit clicking? Is it the exterior signal lights, the signal indicator in the dash or all of them that aren't flashing?

 

Do your four ways work?

 

I'm sorry I should have given more info. This is on a 2001 dodge ram 1500 4x4 5.9l OR. I can here the unit clicking. It's really fast like a bulb is out but I changed the bulb and still the same think. I looked over the wiring but nothing looked bad. I'm kinda confused on what to check next. I'll check my four ways when I get off.

 

See if you are getting power to both front and back turn bulbs. Got a trailer harness by any chance?

 

Yeah I do have a trailer harness but I'm pretty sure it is factory.

 

Exactly. They are notorious for causing some issues.

 

Ohhh boyyyy. I will go through that then. I've always had this random wire that leads to no where. I've never had a problem with it. It looks like someone may have added it before.

 

Okay I figured out that all the flashers work but the rear left one which is the problem one
