Hey guys.
My c43 turns on like it should, but for every 5x that it turns on, 1x it will start than turn off RIGHT AWAY. I have to turn key to off than turn it back on and it will start and stays on.
2nd question, after hitting some pot holes in winter my AC will not turn on now.
I checked the fuses and they are ok. What could have happened?
Thanks In Advance.

For first problem, try your second key and see if problem remains. If you don't have a second key, you really need to get one.
Second problem. Very vague, do you mean the head unit panel does not power up at all? If that is the case I would pull it out and check power and grounds. If it has proper circuit 30 power and proper circuit 15 (key on), and grounds are ok, you have a bad unit. Don't see this hardly ever though but you need to start by checking the simple things first.

I don't have a spare but will get one soon. A friend told me to turn the key to the on position each time I start the car. Than turn the car on, so far the car starts each time every time. Maybe fuel pump going bad?Originally Posted by benzslo

The head unit is working accept at night the lights on the controls are off. Maybe the unit is messed up, I checked the wires and all looks good.Originally Posted by benzslo
