Had a coworker notify me yesterday that my driver side brake light was not working.  Upon investigation, I found that when I press the brake, the driver side Brake LEDs flash but wont stay lit as I hold the brake (passenger side and top brake light working fine).  Obviously it cant be a bulb, so I figured must be a fuse, right? But I do not see any fuse listed as being for our brake lights.... Anybody got any suggestions on what it might be??

Based upon your past Forum posts, I expect this information will equip you for a likely DIY repair.

 

The online 2017 Edge Workshop Manual describes the Body Control Module (BCM) role in stoplamps operation…

And the quasi-fusing effect of the above-mentioned Field Effect Transistor (FET) in stoplamp fault conditions is described as…

Here is the full Stoplamps Diagnosis and Testing Procedure, though your need is only for the “One Or More Stoplamps Are Inoperative” portion, which I have expanded for the Rear Lamp Assembly Left Hand connector testing detail,

…and hopefully won’t progress to additional testing involving this Body Control Module (BCM) connector…

Dude... That is the most in-depth, thought out, just awesome reply I could have ever asked for.  Thank you so much for taking the time.  I am no mechanic, but I do electrical/hvac work for a living and I can't wait to start testing those outputs tomorrow.  Although, I suspect this will end with me buying a new taillight at $350..  Thanks again

Based only upon the Workshop Manual info, I also was concerned for you that a high-dollar assembly replacement might be necessary.

 

Good luck!

LEDs do fail. I wonder if it's possible to replace the individual LEDs? Should have set a code. You have any tester to read DCTs?
