How to replace the Neutral Safety Switch on Pontiac Grand Prix?

To remove the switch, unbolt the ground cable from the battery, and the Theftlock audio system lockout if present. Move the transaxle into the NEUTRAL position and thereafter, jack up the vehicle and thereafter support the vehicle on two jackstands. Start from the Neutral start switch and follow the wire harness right up to the connector; remove the connector from the retention clips. Lift back of vehicle and disconnect electrical and vacuum connectors from cruise control servo if equipped, remove servo and place to side. Finally, after the nut is removed, separate the shift lever from the transaxle, and after some other bolt removal, separate the switch. If the original switch is to be reinstalled simply scribe a line on the switch mounting bracket around the heads of the mounting bolts to assist in correct alignment. In setting the switch, engage the flats on the shift shaft with those in the switch and lower it on the shaft then fix the bolts. If both the switch blades are new and the shaft is not in use, then the four bolts available must be tighten; but if an adjustment needs to be done, the four bolts must remain loosened. For adjustment, bring the outer notch in the switch into contact with the inner notch of the shift shaft and then tighten the switch bolts. Last but not the least, connect the third negative cable and check if the engine starts only in Neutral or Park only.

Pontiac Grand Prix Neutral Safety Switch

The Pontiac Grand Prix Neutral Safety Switch prevents cranking unless the shifter is in park or neutral, so every ignition attempt is safer for the driver and bystanders. Neutral Safety Switches are wired in line with the starter circuit. The Neutral Safety Switch monitors gear position and allows electrical current to reach the starter motor when the lever is clicked into the neutral or park position. When the lever is in the drive or reverse position, the Neutral Safety Switch breaks the electrical circuit and the engine does not start. This prevents the vehicle from moving unexpectedly. Over the years, the function of the Pontiac remains the same, so whether the driver is in an early Grand Prix coupe or a later Grand Prix sedan, the experience is the same simple pedal-free safeguard. All the versions use a set of contacts inside that open or close with lever movement as opposed to electronic sensor arrays. Therefore, the main difference between model years is simply connector shape and mounting bracket style as opposed to how the Neutral Safety Switch actually operates. This simple design allows Pontiac owners to quickly determine if a starting issue is due to a lack of power at the starter feed by toggling the shifter to see if the Neutral Safety Switch has maintained its protective gate.

Each OEM Pontiac Grand Prix Neutral Safety Switch we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
