Blinkers

[14gen1]

Hello, looking for any help with diagnosing why my driver side turn signals aren't working...they work on the mirror, and the light flashes normally on the dash, but for whatever reason they're not lighting up when I turn on the left hand turn signal.

Check to see if the blinker fluid is low. Are the lights on the dash blinking very fast? Check the easy things first. Try new bulbs.

Blinker fluid is topped off. The dash is normal, and the mirror blinkers still work. The front and rear blinkers do not though

Try your hazard lights to see if both sides are working. I still would try new bulbs if the lights on the left are not working.

Hazards only work on the right side

Following, same issue on the P-side blinker on my 2012 3.5 ecoboost.

I'm having the same problem except it is hyperblinking on the dash, checked fuses those were good minus fuse 4 which is blown and now the truck won't start and dash goes crazy. So need to fix that. Hopefully truck starts agter replacing fuse 4. But back to the turn signal, narrowed it down to a break either between the fuse box in the engine bay, or it could be as extensive as going into the steering column. It has nothing with the interior fuse panel because those were getting power.

A friend of mine thinks that it could be the BCM. The issue with that is that you have to have a Scanner that is “forscan” compatible or it won’t show a code. Going to try tomorrow and see what the results are

Sounds like a short or an electrical gremlin to me
