1. Faulty Ignition Switch:
The ignition switch may be worn out or malfunctioning, causing the engine to not turn off completely. When the key is jiggled, it makes temporary contact, allowing the radio to stay on.
2. Electrical Wiring Issue:
There might be a short circuit or loose connection in the electrical wiring near the ignition system. This can interfere with the signal that turns off the engine and other accessories.
3. Starter Relay Problem:
The starter relay is responsible for providing power to the starter motor. If the relay is faulty or has loose connections, it can affect the proper shutdown of the engine.
4. Malfunctioning Engine Control Module (ECM):
The ECM is the central computer that controls various functions in the vehicle, including engine operation. A software glitch or hardware failure in the ECM can affect the engine shutdown process.
Recommendation:
Given the potential safety and reliability risks, it's advisable NOT to rely on this workaround by jiggling the key. It's important to schedule a professional diagnosis with a qualified mechanic or dealership authorized to work on Saabs.
They can accurately identify the underlying cause and perform the necessary repairs to ensure the proper and safe function of the vehicle's ignition system.
