Two problems related to wiper have been reported for the 1998 Ford Expedition. The most recently reported issues are listed below.
The contact owns a 1998 Ford Expedition. The contact stated that while driving 35 mph in rainy weather, water began to leak into the vehicle from the windshield area. The vehicle was not taken to the dealer for inspection. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 81,000.
We have our Expedition for a while and we know the people who owned it before us. While it is raining and days after the power to the truck does not turn off. The radio will turn on, the blower for heat or air will keep blowing, the lights will turn on, the four wheell drive will stop, abs will stop, and the wiper blades will not work. So because the electrical items will turn on at random, they drain the battery and the truck will not start the next day. We found out that due to manufacturing error, the windshield leaks water into the general electric module. The other problem is the part not only expensive, but if you buy one and it does not work, it is not returnable. And that was told to us by multiple dealerships. So basically Ford knows of the problem and it is a safety issue and has done nothing about it.
