How to replace the turn signal flasher unit on the Mercury Mariner?

This method is only for 2004 and earlier models. After that, there is a Smart Junction Box in the car. The dealer service department will need to diagnose the problem with this. Besides, both turn signals work through one electronic flasher unit installed under the instrument panel. Rapid flashing on one side of the turn signal indicator shows that a bulb has burnt out. If this does not happen, it could be because of a blown fuse, faulty flasher unit, broken switch, or loose connection. When it is necessary to change the flasher, it should be taken out from its mounting bracket first and then disconnected from its electrical connector. Before installing a new flasher compare an old one with it.

Mercury Mariner Turn Signal Flasher

The Mercury Mariner Turn Signal Flasher is designed to keep the driver safe by rhythmically supplying power to the blinkers so that other traffic will know when your vehicle is going to turn or stop in the case of an emergency. The first Mercury models contained a thermal Turn Signal Flasher that was mechanically driven. Current ran through a spring steel strip, heating the metal to bend it. This bending opened and closed the circuit. A clicking noise was produced along with a steady on-off pulse sequenced in this way at each corner. Over time, versions of the Mercury Mariner began using a solid state electronic Turn Signal Flasher, which replaced moving parts with transistors and timing chips. This enabled these flashers to operate reliably with low draw LED lamps and with multiple bulbs without relying on heat. The compact design of each Turn Signal Flasher allows it to sit in the fuse box, which comes to life the moment the lever moves. Contemporary owners of a Mercury Mariner enjoy a unit that responds to stimuli faster, resists wear better, and is even able to reproduce that vintage click sound to provide feedback to the driver. Every Mariner depends on a correctly matched Turn Signal Flasher to ensure the signal and hazard lights stay flashing whenever the stalk is engaged.
