My 4x4 light is flashing while I'm driving. I tried to turn my truck off and turn it in 4-wheel low and high and them back into 4 awd and it's still flashing. I've never seen it do it before. Is there a way to get it to turn off?

Hello,

This light blinks when there is a problem with the 4 wheel drive system with usually is the encoder has gone out. Here is how you replace the encoder (actuator). Check out the diagrams (below). Please let us know what happens.
