Here's a breakdown of likely causes and what you should do:
* Low Brake Pedal Travel/Brake System Issue: The most common cause. If your brake pedal feels unusually soft or spongy, there might be insufficient pressure to release the interlock. Have your brake system inspected, including checking brake fluid levels and for leaks. Low fluid is a serious problem and needs immediate attention.
* Steering Wheel Position: Some Grand Prix models require a slight turn of the steering wheel to disengage the interlock. Try gently turning the steering wheel back and forth while pressing the brake pedal.
* Shift Interlock Cable/Solenoid Failure: The cable or solenoid that connects the brake pedal to the shift lever may be damaged, frayed, or broken. This requires professional repair as it's often not a simple fix.
* Faulty Shift Lever: Less likely, but the shift lever itself could be malfunctioning. This is also a repair best left to a mechanic.
* Steering Column Issues: In rare cases, a problem within the steering column itself could interfere with the interlock. This is less likely given the clicking noise is localized to the steering column.
What you should NOT do:
* Force the shifter: Trying to force the shifter out of park can damage the transmission or the interlock mechanism, potentially leading to expensive repairs.
What you SHOULD do:
1. Check your brake fluid level: This is the most important step.
2. Try gently turning the steering wheel while depressing the brake pedal: See if this releases the shifter.
3. Have your vehicle towed to a qualified mechanic: Don't attempt to drive the car until the problem is diagnosed and fixed. Explain the clicking sound and the inability to shift out of park. They have the tools and expertise to properly diagnose and repair the issue.
Ignoring this problem could lead to you being unable to move your vehicle at all, so prompt professional attention is strongly recommended.
