Left tail lamp not operational.

[laminarflow]

Hey everyone!

 

I have a 2015 Sierra 1500 and the driver's side tail lamps/running lamps are not operational. Looking for ideas as to why. Lots of stuff breaking at 120000 KM ... sigh!

 

Brake lights, turn signals, plate lamps, and reverse lights are ALL operational. I've checked the basic wiring around the lamp. The fuses are fine. The ground is clean and secure. The brake-filaments in the bulbs appear to be intact. No moisture in the lamp housing.

 

Anything I'm missing? Probably!

 

Thank you for your help/consideration.

I would try changing the bulb just to see if that's a easy fix.

Just spent $28 on new bulbs to rule that out - not the bulbs. No dice. Any other things I'm missing?

On my 2017 Silverado the right turn signal was out.  They replace the harness to the light under warranty.  Said it was corroded somewhere.

Right side of my 2014 - took a new harness to solve the issue. Lots of debris gets thrown onto the connectors under the light housings.....was ~$60.00 from Rock Auto
