Here's why:
* Internal short or malfunction: The switch inside the stalk can develop a short circuit or simply fail, causing power to constantly flow to both the hazard and turn signal circuits.
* Faulty wiring: While less likely, damaged or corroded wiring connected to the turn signal switch could also cause this issue. Moisture intrusion is a common culprit in older vehicles, particularly convertibles.
* (Less likely) Multi-function switch module: In some vehicles, there's a separate multi-function switch module that controls various functions including turn signals and wipers. While less common as the primary cause, a malfunction here could also be responsible.
Troubleshooting steps (do these at your own risk. If unsure, consult a mechanic):
1. Check the fuses: Start by inspecting the fuses related to the turn signals and hazard lights in your fuse box. A blown fuse could be a symptom, but a short is likely to blow the fuse again immediately.
2. Test the hazard switch: Try switching the hazard lights on and off. If they work independently but then the issue returns with turn signal use, the problem is more likely in the stalk.
3. Inspect the turn signal stalk: If possible, carefully examine the stalk for any visible damage or loose connections. This is often difficult to do without removing the steering wheel and column covers.
4. Try the turn signals: Test all turn signals (front and rear). If one side doesn't work, but the other side works, the problem could be in the wiring to that specific side, rather than the stalk.
Important: Because this often involves electrical work near the steering column, if you're not comfortable with automotive electrical systems, it's best to take your Sebring to a qualified mechanic for diagnosis and repair. Incorrectly working with the steering column can be dangerous.
