    Hi, I have a 03 Silverado and the 4x4 would not engage. I changed the actuator on the differential and I have 4 wheel drive but my new problem is the 4hi and 4lo just flash when in 4 wheel no solid light.

    More than likely it's the dash switch , common problem. You can also check the ground wires, drivers side about the middle of the door , they're attached to the cab mount , remove ,clean and tighten. The switch runs about $80 .

    Thanks for the reply

    Ticki2, Thanks for your reply I was thinking of checking the switch. I will check the wire's under the truck. Someone told me I could of installed the wrong actuator because the lights change when the actuator is engaged.
