How to remove and reinstall the Turn Signal Switch on Mercury Mariner?

If it is a 2004 model or an earlier one, you should first of all disconnect the negative battery cable and remove the key lock cylinder and steering column covers. Then, you have to unplug the electrical connector from the Turn Signal Switch and take off the switch by removing its retaining screws. The battery should be reconnected and reinstall by reversing the removal steps. The PCM is going to need a relearn procedure for optimum performance. For 2005 models and beyond, you will need to disconnect the battery cable, remove the steering wheel, drop down the tilt steering column, and uncover the steering column. Next is to tape clock springs with screws on 2005-2007 models as well as detach wiring before proceeding with Turn Signal Switch removal. Installation follows the reverse procedure.

Mercury Mariner Turn Signal Switch

The Mercury Mariner Turn Signal Switch allows the driver to indicate every intended lane change or turn and helps keep traffic safe. Fitted in the steering column, the Turn Signal Switch makes use of a lever which, when tipped, closes an electrical circuit that flashes the indicator lamps of the Mariner. It also cancels automatically once the wheel is centered. The same stalk serves as a host for the rotary dials for headlights, fog lamps, wiper speeds, and cruise control buttons on many Mercury models. With one Turn Signal Switch, lighting and convenience become a hub. The original Mariner versions had a simple mechanical canceling cam. Later Mariner vehicles got added multifunction circuitry that would handle other lighting tasks without more dashboard switches. This packed more features into the Turn Signal Switch itself. The main distinction between the two styles is their complexity. The Mercury design is easier and utilizes an all-in-one printed circuit module that reduces separate wiring harnesses. The importance of a responsive Turn Signal Switch cannot be overstated regardless of generation. A sticking or failed contact may hinder the ability of the Mariner signals to warn surrounding traffic. Thus, the Mercury system's core communication may be made less effective.
