Once you have found the neutral safety switch, follow these steps to adjust it:
1. Check the nut/bolt holding the switch in place. If it is loose, tighten it until it is snug.
2. Turn the key in the ignition to the "On" position. If the starter engages, your adjustment is complete. If it does not engage, move on to the next step.
3. Pull the transmission linkage towards the front of your car while the key is in the "On" position. Hold it in this position.
4. Loosen the nut/bolt holding the neutral safety switch in place and reposition the switch so that it is closer to the transmission linkage. Be sure not to move it too much or the switch may not engage fully with the linkage when the transmission is in Park.
5. Tighten the nut/bolt and repeat steps 2 and 3 to test switch operation.
Continue repeating steps 4 and 5 until you find a position for the switch that allows it to engage fully with the transmission linkage in both the "Park" and "Neutral" positions, and that also causes the starter to disengage when the transmission is in any gear other than "Park".
