Truck will not start, left blinker will no work and dimmer switch is bad

Left blinker works only when I manually engage it by click blinker up and down and dimmer won't work at all. Won't engage or click when you try to dimmer lights
Truck was starting. Then it got to the point that you had to turn ignition forward let off just a little and it would start. Now it does nothing. All lights on instrument panel are coming on and everything. But won't hit a lick.
