Keep your courtesy lighting and trunk-ajar warning working correctly with the Standard Ignition Door Jamb Switch / Trunk Open Warning Switch (DS-337). It installs as a direct-fit replacement for the listed applications: the 1986-1988 Ford Escort and 1988 Ford EXP. This part is cataloged under both names, so you'll see it listed as a door jamb switch and as a trunk open warning switch.
Mechanically, this is a plunger-actuated switch that senses whether a door or rear lid is open or closed and signals the vehicle's lighting and warning circuits accordingly.
Signs this switch may need replacing include an interior light that stays on or won't come on, or a trunk-open warning that stays lit or never illuminates. Diagnose the circuit first; if the switch is the cause, this replaces it.
Interchange: S1046 · SW128 · DJ6345 · E8EB15N562AA · E8FZ13713B · SW2191 · Manufacturer part number DS-337 (also DS337)
