There's been a lot of problems with faulty switches on the 99-06 trucks. Many have been replaced. Do a search. You can order the switch at a reasonable price. I had the switch problem on my 04 and the dealer did some sort of reprogram. So that may be an option too. If the truck is in 4x4 you need to get it out. Others might have a better suggestion, but a battery disconnect might reset the switch and allow it to put the truck back in 2wd?

i'll try the battery thing first(to get it out) i'm kind of wondering how it went in by itself to begin with ..... i couldn't find a search option on here ,i'll look again Thanks!!!

I had an issue on my wife's '99 Jimmy where it would randomly say 'service 4x4' and wouldn't change from the drive mode it was in. After checking all fluids, sensors, etc. I determined it was the switch, and for less than $50 (bought it at CarQuest, everyone else said it was dealer only) the problem has been gone for almost a year.

YEAH I'VE SEEN A LOT OF ENCODER RING SENSORS IN WHICH CASE YOU WOULD JUST NEED TO BUY A SENSOR A GASKET AND FOUR NEW BOLTS, THERE IS ALSO A PROGRAM FOR THAT ISSUE WHICH GETS RID OF THE PLAY THAT CAUSES IT THE FAILURE TO BEGIN WITH

MY TRUCK DID THE SAME THING TO ME....IF YOU JUST REPLACE THE PUSH BUTTON SWITCH IT WILL BE OK...THEY CRACK ON THE BACK SIDE OF THEM AND IT MAKES THEM GO BAD.....I BOUGHT MINE OFF EBAY FOR 40 DOLLARS. IF YOU PULL YOU DASH BOARD OF AND WIGGLE THE SWITCH...AND HIT THE 2WD BUTTON IT WILL COME OUT OF "AUTO" AND YOU WILL BE OK.....BUT YOU STILL NEED A NEW SWITCH...

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
