Lights on push button 4 wheel drive out

It could be a junk switch or it could be bad contacts inside the transfer case motor.. Does the transfer case switch to the selected gears? Everytime? If so, you might try another switch. If it does the same, I would say the motor contacts are bad. Replace the motor if you want the lights, But I personally wouldn't do it until the motor quit switching gears. They're not cheap.

hi
yes seems like you switch is faulty.]
replace the switch
Thanks

Try replacing the switch, they fail often.

If your truck has a dashboard push-button 4x4, then carefully disassemble and clean with Q-tips and alcohol. when 4x4 lights turn off, drive in reverse over 15 feet. Good luck.

maybe its just the indicator thats not lighting up

Most likely the controller module is bad, or the actuator for the front axle has gone bad.

no fuse...mine was stuck in low and i had to replace vacume hose in the transfer case about 200.00 bucks

I just fixed a friend of mines 96 yukon...shift to neutral press 4H and u can hear the actuator make noise (we even replaced it with a new one his idea and the same thing happen as old one), so as he hit the switch for 4H i layed under it (on 4 jack stands) and I could hear the motor on the transfer case make a loud noise (well thats working) and before all this I asked him did u check all your fuses (he said guarnteed to be all good) one night it was bothering me so i looked through the owner manual for the yukon and in the fuse box on driver side by the door there are (2) fuse for the 4wheel drive unit,pull one of the fuses good...pulled the other one and it was blown put in a new fuse and it works like brand new..pull fuse for anything that has to do with 4 wheel drive componants,

There is an electric motor that engages drive.  Mine was stuck and a mechanic beat it w a hammer while I was in vehicle w brake on in drive pushing the diff 4wd buttons.  It freed up and started working fine!!  It looks like a small starter under car on passenger side. Or buy one on ebay  for cheap and replace it
