My lights on my dash are not working. They lights around the odometer. I tried my 4 wheel drive today and it will not come on as well. Could that be related to the lights and maybe a bad fuse.

most dash lights can be dimmed or switched off check this first, then trace the wiring from the switch to the dash lights for a bad connection.

Something you can do is to tap the 4/4 motor under drivers side on the back of transfer case with key on engine off. Have someone work the buttons as you gently tap the motor. Don't hit so hard as to dent it. Usually works.

Since this is done electrically today with no light on dash I would check the switch that you move to engage the 4X4 action.

first put the van in neutral while in neutral try moving the shift

I was researching the recalls for the 2002 tundra and havent found any recall pertaining to the 4whl drive. Sometimes when people have their 4wheel drive locked in and drive on pavement for any length of time, whether it be just a couple of feet or a couple of miles, over time it creates a binding of the gears in your transfer case. Once the bind is so great, the engaging and disengaging starts malfunctioning and leads to bigger problems overall. I could be wrong about this being the problem that you have but I think its something to look into. It wouldnt hurt to put your vehicle up off all fours and release the bind if any by running through the gears while in 2 and rour wheel drive while all four tires can move freely and release. See if that works for you. Check your gear oil front , center and rear and use much caution when attempting this suggestion. Also refer to your owners manual troubleshooting section for other possibilities. Merry Christmas. By the way, the electrical switch should be covered in the troubleshooting section also.

If your lights are working correctly on the dash and not just blinking,Double check the hubs are locked in if not automatic ones.

it could be a blown bulb cuz they are all on the same curcit

check your relays first (after the fuses) and the vacuum lines if you have those for the 4 wheel drive. Hope that helps

check your fuses under the dash... one of them is blown
even tho it's not flashing on the dash board... can you hear the clicking of the turn signals ?

Push the "2 hi" switch while you're driving it.

You can do this while you're driving, as these systems have "shift on the fly".

You will hear / feel a "clunk" when the system disengages, and you will see the "2 hi" light come back on..
