I need help please. I changed the battery in my 2009 challenger and now for some reason the blinkers, horn, wipers don't work and I have the stability control lights are on. What did I do wrong. Everything worked before replacing the factory battery.
This may work. The PCM is corrupt. Remove the battery cables again. Get them away from the battery and hold them together for at least 30 seconds. This will discharge all the memory capacitors in the PCM. Put the battery cables back on and see if the car is back to normal.
