What is the Park/Lock system and how do you remove and install the Neutral Safety Switch on Chevrolet Avalanche?

The Park/Lock system prevents the shift lever from moving out of Park without depressing the brake pedal and the ignition key from being removed unless the shift lever is in Park. To remove the actuator, park the vehicle in Neutral, set the parking brake, and disable the airbag system. Disconnect the wiring and pry off the actuator from the cable shift cam and steering column. Snap the actuator onto the cable shift cam and steering column cover and reconnect the wiring. Press the adjuster block to disengage the internal teeth and slide it away from the actuator. To install the actuator, push the tab to lock it in place and reconnect the battery. Check the operation by ensuring the lever can only move out of Park when the brake pedal is depressed and readjust if needed. Finally, reinstall the knee bolster.

Chevrolet Avalanche Neutral Safety Switch

Chevrolet Avalanche Neutral Safety Switch is a gatekeeper that allows the engine to crank only when the transmission lever is in park or neutral to protect drivers and bystanders from unexpected movement of the vehicle. This little electrical device is located in the factory Chevrolet starting circuit and is responsible for monitoring the position of the gear and opening up the circuit as soon as the shifter slips into drive or reverse. It closes the circuit when the selector is in the safe slots. The Neutral Safety Switch is based on simple but effective contacts that are aligned with the gear selector. When the contacts are in the proper position, an all-clear signal is sent, allowing ignition. If the selector is in any unsafe gear, the contacts will remain open, cutting off current to the starter solenoid, and the engine will stay off. Throughout the production run of the Avalanche line, the Neutral Safety Switch has maintained this same basic function and layout. This means that owners will be exposed to one design throughout the life of the product, as opposed to having to contend with multiple generations of the product undergoing drastic revisions. Symptoms of a failing Neutral Safety Switch include silent key turns, intermittent starts, or the need to wiggle the shifter into place to crank. Testing the Neutral Safety Switch with a simple continuity check can be applied to confirm that the switch is healthy and keep every Chevrolet and every Avalanche rolling smoothly.

Each OEM Chevrolet Avalanche 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.
