Hey guys.. I have been having problems with my 2004 chevy silverado. When I first start the truck it will go in and out of 2hi and 4hi no problem but when I drive it for a bit in 2hi and then put it into 4hi or auto4x4 and then try to put it back into 2wd it will not go back into 2hi!! It gets stuck in 4 hi or lo... I can hear the actuator trying to disengage 4x4 but it just pops back into 4x4. If I let the truck sit for a couple hours it will go back into 2hi.

Any suggestions :cheers:

2 possible issues come to mind. Eother the mode switch in the dash or the encoder sensor on the side of the transfer case. Not sure without some scan data.

I had a similar problem with my car, but it only hapend when I used the hypertech power programmer on my car and the control module broke on me.

      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!

      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.
