WARNING: This page is about a different car, the 1997 Mercury Mountaineer and 1997 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Unplug relay, located behind top right of instrument panel. Test for continuity between relay terminals No. 1 (Brown/Light Blue wire on mating connector) and No. 5 (Gray/Light Blue wire on mating connector). Continuity should not exist.
  2. Connect battery voltage between relay terminals No. 2 (Orange/Yellow wire on mating connector) and No. 4 (Purple/Orange wire on mating connector). Again test for continuity between terminals No. 1 and 5. Continuity should exist. If continuity is not as specified, replace relay.
