Inertia Switch

Ensure key is off. Inertia switches may be found in the following locations:

On Aerostar & "E" Series, on right kick panel, just forward of door opening.
On Bronco & "F" Series, on floorboard to left and above steering column.
On Explorer & Navajo, under instrument panel, to right of transmission hump.

Push down on reset button to ensure switch is closed. Measure resistance between terminals on switch. If resistance is 5 ohms or less, switch is okay. For additional circuit testing information refer to CIRCUIT TEST J in TESTS W/CODES EEC-IV article. If resistance is greater than 5 ohms, replace switch.

NOTE: In closed position, reset button can be depressed an additional 1/16" against spring. This is normal and does not affect switch operation.
