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

      Today I filled up with 4.899 gallons of fuel at a cost of $4.899 a gallon. $24 bucks. 290 miles. 59.2 mpg. After my 4% COSTCO discount just under eight cents a mile.

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.

      Checked the pads today and there's plenty of meat on them. If the message keeps coming up, I'll just answer YES that the pads were replaced and wait for the squeal.
