I notice the RPM needle and turn signals stop working. When I turn the truck off. It won’t start. I change the ignition E 10 amp fuse and it starts right up with everything working. Also the 4 wheel drive selector switch changes all the time when I turn on the key ie; 4 low, 4 high, or neutral. Could it be ignition switch or 4 wheel drive selector switch?

Good afternoon,

I attached the fuse diagram for your truck for ignition E.fuse.

In order to find out what is causing the fuse to fail, you need to disconnect what the fuse controls to see which component is causing this.

It could be the instrument panel, turn signal switch, park/neutral switch or the A/C compressor relay.
