It's the transfer case motor.I had the same problem exactly and replaced, now it works great. Part is about $100.00 ( aftermarket ) .Ifyou are going to replace yourself you will have to remove front drive shaft and remove yoke from transfer case with an impact wrench for clearance to remove transfer case motor . When you put the new transfer case motor in make sure you line up slot with grove in transfer case motor. Good Luck.

    When replacing the motor you need to disconnect the battery for about
    10 minutes then reconnect it,this resets the computor.

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.

Four wheel drive lite is blinking and wont go out


Hi, You will need to take to mitsubishi dealer and have them scan your diagnostics. But this is a common thing in montero's and it sounds like o ring (which is plastic) in transfer case has busted. As long as it switches in and out of 4 wheel drive it is ok to drive. If it doesn't, dont drive it...it could cause alot of damage.

Had the same problem. Easy fix. Grasp the plastic dashboard piece that goes around the instrument cluster and 4 wheel drive switch and pull off. Remove the 4 wheel drive switch. Unplug wiring harness from back of switch. use small screwdriver and carefully bend all metal tabs in back of switch slightly to one side. Re-install harness and switch back into dash. Should work fine, it just was not getting a connection. Worked great for me.
