Hello I need help with my 2000 Sierra the other day I was driving threw and puddle and my service 4wd light went out and I was stuck in 2wd I've replace the switch and the transfer case motor that engages the 4wd and still nothing but when I first unplugged the switch my service 4wd light went away but still does not work

 

Ps the motor is not trying to move there no sound coming from it right away

 

Thanks for the help

Have you checked all of your fuses? Water and electricity cause disasters in an instant. I'd verify every fuse is in good working order first. Then I would check the voltage on the transfer case motor.

There is a fuse for the transfer case and there will be one for the front differential actuator. Need to check both fuses. On mine I have the ATC fuse for the transfer case under the hood and a 4wd for the front actuator in the driver's door jamb fuse block.

      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!

      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.

      Welcome to the Forum! Always post the code definitions along with the codes. there are over 18000 possible codes, no one remembers them all and most will skip over your post rather than look them up
