2001 4x4 not working

My 2001 tundra 4 wheel drive not working at all. 2 wheel is fine. 2 wheel 4 wheel push buttons don't even light up. Any ideas or suggestions

 

Check your fuses. Then check out the wiring going to your actuator on the transfer case.

 

No lights = controls are not getting power.

In the dash specifically there's a fuse marked 4WD. Replace it.

If anyone touched your stereo recently, you'll want to check the connectors on the back of the center dash. Some dumbass may've cut a harness. People who cut factory harnesses to install stereos are assbags.

 

Thanks I will check it out

 

Also just check that you’re engaging it properly. Read the manual.
