Why is my car's turn signal flashing quickly?

Model: (Various brands) Various
Part: Side marker light

Video tutorial

This video tells us that when the arrow flashes quickly, this is a symptom of a burnt-out bulb: its filament breaks and this interrupts the circuit in that bulb, drastically reducing the electrical load on that side. The control unit detects this lower resistance and interprets this problem as a failure.

To clearly and immediately alert the driver, it doubles the flashing speed of the indicators (both on the dashboard and outside). This failure can affect all turn signals, not just the rear one: on some models, even the side position light could be involved.

Other causes could be a loose or oxidized bulb holder; damaged wiring, or an LED bulb installed without an adapter (their much lower consumption misleads the control unit).

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
