Repair Cost: The cost of repair depends heavily on your location and whether you have the work done at a dealership, an independent mechanic, or if you attempt it yourself.
* Parts: The neutral safety switch itself is relatively inexpensive, usually costing between $20 and $50. However, you might need additional parts like new connectors or a new shift cable depending on the specific cause of failure.
* Labor: Labor costs vary significantly. A dealership will typically charge the most, while an independent mechanic will be more affordable. Expect to pay anywhere from $50 to $150 or more for labor, depending on the complexity of the repair (some require dropping the transmission pan for access).
* DIY: If you're mechanically inclined, you can often replace the switch yourself. This would save you the labor cost, but you'll need to consult a repair manual or online resources for specific instructions as it can be a somewhat tricky job.
In short: While the neutral safety switch is a likely culprit, it's not the *only* possibility. Other potential issues (though less likely given your description) include:
* Weak battery cables or connections: Even if the battery tests good, corroded or loose cables can prevent sufficient current flow to the starter.
* Faulty ignition switch: This is less probable given you're getting a click, but a failing ignition switch can prevent the starter from engaging.
Recommendation: Start by having a mechanic or auto parts store check your battery connections and the NSS. If the NSS is indeed the problem, get a quote for the replacement before authorizing the repair. If the problem persists after a switch replacement, further diagnostics will be needed.
