Can a bad neutral safety switch on 1999 Jeep Cherokee prevent it from starting?
Yes, a faulty neutral safety switch (NSS) on a 1999 Jeep Cherokee can absolutely prevent it from starting. The NSS is a crucial safety device that prevents the vehicle from starting unless the transmission is in Park or Neutral. If the switch is malfunctioning, it might not send the correct signal to the ignition system, effectively blocking the starting process.
