Car will start up and run, I stop go in to the store come back out car will start up then shut off 2 sometimes 3 times them start back up and run. Everytime I run the car the Dash tells me all my doors are open, the trunk is open, check temp, check brakes every warning signal is going off. The speedometer and tachometer do not work. The blinkers work outside but not inside. The heater fan does not work. The cruise control does not work. But the gas gauge, heated seats and radio all work fine. What is going on here?
