Default turn signals and heater fan not working?

my turn signals and heater fan stop working sometimes. if i get in my car start it and go the gas station, they will work until i get there. when i start it back up they sometimes dont work. also if they are not working, sometimes they start working again.

Sounds like a wiring problem. A loose wire or bad ground possibly. Sometimes fuses can loosen or build up corrosion but I thought those were on separate fuses.

Next time it happens, wiggle the key a bit and give the underside of the column a whack or two. If it changes, ignition switch.
