Mercury Ignition Switch

Replacement Ignition switch. It all starts here. If your car or truck shows no signs of life, even though you know your battery is good, the next place to look is at the ignition switch. Replacing your car ignition starter switch can also be good preventative maintenance.

Some possible symptoms of ignition switch malfunction:

  • Excessive movement of the lock cylinder required
  • Loss, or intermittent operation of certain accessories
    • Wipers
    • Radio
  • Vehicle has power but no noise from starter when start position engaged


Ignition switches are generally a basic replacement.

  •  
    • Locate the switch on the column; it is usually above the drivers shins, up under the dash. Some vechles may require AC ducts to be removed.
    • Remove and replace
  • Column Mounted: Dash mounted:
  • Disconnect the battery
  • Remove the lock cylinder
    • MOST APPLICATIONS
    • Turn the switch to the accessory position
    • Insert a straightened paper clip into the hole; there is a small button you press with the paper clip end
    • The key should now move further counter clockwise, and the key and cylinder should come out
  • Remove the bezel that holds the switch
  • Unplug
  • Make sure your new switch matches
  • Reverse the procedure to reinstall, the key and cylinder go in by inserting the same way as they came out and turning back to the normal position.
