i live in NJ. we just had this big snow storm and i thought no problem, i would the 4x4. Friday it the truck (96 tahoe LT) was sitting in the parking lot cold and started it up and started moving and while still cold hit the 4x4 HI button. the 4x4 HI button started to blink and there was a huge and loud clunk and it went into 4x4 HI and the light was steady on in 4x4 HI. so i was driving it until saturday in 4x4HI with no problem switching between 2Hi and 4HI. so saturday night i parked the truck and came back and started it up and the 4HI light was flashing. i started driving and it would not stop flashing. i pushed the 2HI it the light was steady on in 2HI. i pushed 4HI and it would not stop blinking in 4HI. it would stay blinking indefinitely. so now i have no 4x4 only 2wd and my truck slips all over the place in the snow. i did try to put it in 4LO and it went in but only the rear wheels turned not the front. could it be the actuator?

 

Anyone have any thoughts?

 

thanks

I had the same problem with my truck, I have a 2000 though, so not sure if it's the same. What happened to mine was the same as yours though and my service 4wd came up in yellow. I took it to the dealer and they replaced the 4wd switch on transfer case. Not sure if yours is the same as I have AUTOTRAC but sure sounds like it. Anyways good luck with it. When I picked mine up I asked how did you find it, and with the most s**t eating grin I ever seen the service guy smiled and said " THE COMPUTER TOLD US " and yeah it was right.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Z45 · Posted

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
