Rear turn signal issues

[Knox]

So question for the electrical folks

Issue: My rear drivers side turn signal does not work. Verified with 4 ways, 3/4 flash fine, and left signal flashes faster.

Things already checked:
- Bulb is good, I can swap sides the bulbs only work on the right.
- Rear driving lights work fine
- Reverse lights work fine (I know different bulb, but same batch of wires running back there...) I did read a common issue with grounding that the reverse light can get a small bit of voltage leaking to it from the other one but, no, I don't have that issue,
- Took a voltmeter to the pads, and it fluxes up and down 9-10v then 2-4 etc. same as the right side, yet the left doesn't work...

So any ideas? All I can figure is take it apart, clean it all and redo the grounds?

Have you tried it with a test light? If it flashes with a test light it's gonna be your ground.
You could try cleaning the bulb itself, tighten up the socket that it goes in ( ground ). Do you have continuity between the socket and the frame? If not its the wire itself.

Got in the Jeep this morning, rear blinker didn't work (as expected) got to my sons dayhome to drop him off, and it worked... stupid electrical gremlins

So to fix it, do I need to start re soldering the contacts?

Check in behind the body on the rear drivers side (access from underneath) I had and now have more loose connections in there...

This sounds like a broken wire that is inside a wire loom that is somtimes connecting and then not connecting. Also, check the common ground for your rear lights.
