Ok I have running light power to the marker light how ever no turn signal. The rear turn signal is functioning. Test light shows no power. Fuse is good. Not sure what to do or how to fix.

Hello all. I’m trying to trouble shoot my turn signals. I have rear driver side but the front won’t work. I have running light power with a test light just not blinkers. How do I trouble shoot this?
I checked the fuses And relay. Could it be the harness or maybe the ground. Any help would be appreciated.

Hi, I assume by test light, you've checked the individual leads inside the socket, correct? Did you check from the backside of the connector if it's teachable to ensure the problem isn't the socket?
There's flashing on the front lights? (my truck is a different year, so ymmv)
There's some schematics out there for your year. There should be a wire in the engine bay coming out from the fuse box that goes to the front left turn signal. Maybe you can check it in the engine bay where the wire comes out. I'm putting in new wires, they say to use a special anti corrosion grease. This could rule out corrosion that connector.

There are oodles of posts on turn signal diag. Did you read through or use search?

I search and searched, nothing that helps . I thought I would come to the grey beards for help. Checked the socket, running light works with test light, flasher doesn’t. There is a forward facing signal light and one on the fender. Both are having the same problem. I guess I will expose the wire prior in the engine bay and test. I really don’t know where to go if it’s not getting power.
Could it be a grounding issue?

Yes sir, I understand what the problem is I think I just don’t know the solution.

Ok figured it out. It was the turn signal switch in the Column.
