My 4×4 lights up but it won't go into gear is my fuse bad ? And were is it ??
The most common problem is the transfer case shift motor, try tapping on it while someone pushes the 4X4 button, if the motor runs and you have 4X4 then the motor is startingg to fail, if you can't get it to shift then you need to test for a signal power from the gem module to the motor.
