Two problems related to headlight switch have been reported for the 1997 Ford Expedition. The most recently reported issues are listed below.
This issue was at night while driving the headlight to see at night had turned off at a 35 mph speed no bumps no turn just driving straight. This is a serious issue, you use your lights for night and your are left with no lights, as a result for this huge problem I received a ticket that is how I found out my lights were not working. The headlights fuses, module components, wiring were checked no issues there, as for all other lights example emergency lights, rear lights interior lights are functioning. But as the electrician found the directional switch combo was burned left with a white shadow in one area it was replaced, and now functioning. As for the suspension not functioning properly is this an issue that has not been able to be resolved. I have taken it to different shops and there is no air leakage in the suspension pump and other areas that are linked with the suspension. The suspension pump still repeatedly pump air every 45-60 minutes which it's fine, but not when the vehicle bounces very vigorously for 15 minutes or more till it activates the suspension to pump air. When the suspension is down the steering wheel functions different as the bouncing makes it hard to drive at a certain speed, not safe but manageable in the mean while. During this time I'm not appreciating the quality of my Expedition components.
While driving 50 mph, the driver noticed that the headlights were inoperative. This caused the driver poor visibility. The vehicle was taken to a body shop for inspection. The mechanic informed the driver that the multifunction switch needed to be replaced. Combo switch was replaced. Consumer was concerned that the deactivation switch, which was known to cause fires, was not recalled for her vehicle.
