Three problems related to windshield have been reported for the 1998 Ford Expedition. The most recently reported issues are listed below.
When it rains water leaks onto the gem module and fuse box under the dashboard left of the steering column. Some of the effects are, windshield wipers stopping, transmission going into limp mode with od light flashing, battery going dead if raining overnight, speedometer not working, heater fan running while off, left front power window not working, and instrument panel warning lights flashing on and off. Everything comes back to normal after it dries out. I had the windshield replaced. I had the new windshield resealed twice. I had to replace the battery. I still can see water dripping next to the parking brake. I have browsed the net and found that this is a common problem with Expeditions and f150's. I would like Ford to take responsibility and repair this defect.
While driving behind a truck, a rock was thrown against windshield, causing a fingerwide crack from top to bottom of windshield.
While vehicle was parked overnight the glass cracked due to pressure. The dealer will be notified.
