Sometimes there is no sound, no radio, no turn signal, no warning bells from the time I start the truck until I turn it off and restart it. Other times, no issue. Why would this happen?

All of these sounds come from the radio speakers and when the radio or amplifier goes out this will be the result. When you turn the key on then off it resets the amp. These trucks came with an internal and external amplifier depending on which sound system package your truck came with. Here is the location of the amplifier so you can swap it out and if not, you will need to change out the radio for a used/rebuilt unit. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.
