Here's why:
* Can't shift out of Park: The neutral safety switch tells the car's system what gear the transmission is in. If it's malfunctioning, the car might think it's still in Park even when it's not, preventing you from shifting.
* Brake lights come on when applied: The switch often works in conjunction with the brake pedal switch to illuminate the brake lights. A faulty neutral safety switch can sometimes cause the brake lights to act erratically, including staying on or turning on when the brake pedal is pressed.
What to do:
1. Check the brake light switch separately: While it's likely related to the neutral safety switch, a faulty brake light switch is a distinct possibility. Check to make sure your brake lights work when you press the brake pedal, even if the car is off. If they don't work at all, the problem might be just the brake light switch and not the neutral safety switch.
2. Inspect the neutral safety switch: Locate the switch (it's usually on the transmission itself). Visually inspect it for any obvious damage, corrosion, or loose connections. This is often a difficult spot to reach, and you might need to get underneath the car to see it.
3. Test the neutral safety switch: You might be able to test the switch with a multimeter to see if it's providing the correct electrical signals. This requires some electrical knowledge and a multimeter. A mechanic can easily perform this test.
4. Replace the neutral safety switch: If inspection or testing reveals a problem, replacing the neutral safety switch is the most likely solution. This is a relatively straightforward repair for a mechanic, but can be difficult for a beginner due to limited space under the car.
Important Note: Driving a car that won't shift out of park is dangerous. If you can't diagnose and fix the problem yourself, have a qualified mechanic inspect and repair your vehicle immediately. Continuing to try and force the shifter could damage the transmission or other components.
