Common Problems With Turn Signals And How to Fix
Turn signals are essential safety features, ensuring drivers behind and around you know your intentions. Whether you drive a Jeep Grand Cherokee or a Dodge Caravan, a malfunctioning turn signal can lead to confusion on the road and even citations. Understanding how they work and the issues that arise can help you maintain them properly.
How Do Your Turn Signals Work?
Your turn signal system consists of a bulb or LED, wiring, a switch on the steering column, and a flasher relay. When activated, electrical current flows through the relay, creating the blinking signal we all recognize. Some modern vehicles integrate this function with electronic modules for advanced lighting control.
Common Turn Signal Issues And Their Likely Causes
Bulb Burnout
The most common issue, often due to age or vibration damage.
Faulty Flasher Relay
Prevents proper blinking rhythm or stops it entirely.
Corroded Socket
Moisture intrusion can block electrical flow to the bulb.
Damaged Wiring
Frayed wires disrupt current, causing intermittent function.
Defective Switch
Wear over time can cause the signal stalk to fail.
When to Replace Your Turn Signals?
If troubleshooting reveals the bulb, wiring, or relay is beyond repair, replacement is the safest choice. Always opt for OEM-quality components for proper fit, long-lasting performance, and consistent brightness.
