Inertia Switch

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

On Aerostar & Van, on right kick panel, just forward of door opening.
On Bronco & Pickup, on floorboard to left and above steering column.
On Explorer, 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 article in the ENGINE PERFORMANCE Section. 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.
