i have a 2004 c230 kompressor sedan.the car will not start.battery is fine connections are clean and tight. all dash lights,and other electrical components work.when you turn to the start position nothing happens, no click or dimming of lights to indicate power going to starter.could this be related to transmission safety switch?car is in park when attempting to start.where is tansmission computer located.unlike my s class there is no box of computers mounted up in engine compartment.thank you.
