The 4x4 sytem is smarter than you think. It will adjust it's self for slip conditions and knows when you are in 4x4.

Trust all of my eggheads in Detroit, the know what they are doing most of the time. LOL

brake switch may be bad and the truck doesn't know you are depressing the brake to pull truck out of park

your dash cluster is shorting out, replace the dash cluster. simple fix.

Could need a new fully charged battery.

Remove the sender wire from the fuel tank and short it to ground (metal part of tank).

If the fuel gauge goes to full then your sender unit is faulty and replace it.If not ,please come back to me .

Please leave positive feedback if you feel I have helped you.

to coorrect this u will need to pull the gas tank and replace the fuel gage sending unit inside the gas tank, hwerwe is the part number for the fuel module which has the seding unit in it.

The p1682 code is an ignition 1 control circuit code. The p2176 is related to the throttle body. There is a bulletin fron GM on the wiring being rubbed through on the front drive shaft. Have the shop check there first. The first code sounds like a voltage issue, possible ignition switch. Both may be covered under the 100,000 power train warranty. You should call your dealer first to see. Good Luck

Suspect faulty fuel sender. Fuel sender is attached to fuel pump in tank.

The float that moves the gas hand is possibly stuck in the tank. If there's isn't an access hole in the rear of the vehicle you'll have to drop the tank. Unless it becomes free on it's own. Hope this is helpful. Please rate. Thanks

COULD BE A FUSE. CHECK THEM AND YOU SHOULD FIND A BAD ONE. HOPE THIS HELPS. IT IS VERY RARE THAT BOTH OF THE WINDOW MOTORS ARE BAD AT THE SAME TIME. ALSO CHECK THE RELAYS FOR THE WINDOWS. GOOD LUCK. THANKS IN ADVANCE FOR AN HONEST RATING. AND FOR USING FIX-YA. PLEASE KEEP ME POSTED.

hopefully its just the b/u switch (on the trani)

Hi there;
The fuse you are most likely looking for is in the Instament panel fuse block located in front of your left knee. It is a 20 amp fuse & is simply labled AUX. AUX 2 is for the rear outlet.
There is a fuse block under the hood, the fuse you are looking for is a 20 amp fuse & it is in possition #53 that is for the upper outlet in the front.
hope this helps
Farrout!

you do have to drop the tank

Anybody tried rubbing a sticky substance on the "O" ring of the cap? I don't care if it's a candy from a kid, it's worth a try. Clean threads of filler with alcohol real good before too. I'd try taking the cap off, and roughing the threads up with rough sandpaper too, just to give it more bite. Blow threads off good after.

you might have an electric problem since the brake switch comunicates with the transmission module
