The radio would turn on and off without the key in the ignition, the starter tries to start the vehicle without the key in the ignition. While driving down the road the interior lights flicker and the headlights will turn on and off randomly. Automatic door locks will not always work.

Every time it rains. When SUV is parked and turned off the wipers come on. Headlamps and flashers go on and off. Radio turns on and off. Vehicle tries to start itself without key in the ignition. Battery discharges.

It started a year and a half ago. The windshield wipers would come on for no reason. It didn't happen very often at the time I took it in to evaluate the problem. The dealer told me they could not fix a problem they didn't see. Slowly the problem got worst, especially in wet weather. About eight months ago, the headlights would go out if the steering column was lowered. I can no longer raise or lower the column anymore for fear the wipers, locks and headlamps will not work. At times, the locks to the back seat would not respond to the power lock buttons. The rear wiper does not work anymore, you can hear the motor run at times, but no movement. The odometer blinks on and off at times. There have been times it doesn't come on at all. That normally happens when I'm on the road for a long period of time. With all of that going on, the worst thing is to drive the car in the rain and snow and not know if the wipers will work at all.

I bought a 99 expedition used in march 2004, from the local ford dealer in clarksburg, wv. From the 2nd day I had it home it has had electrical problems in the rain. The rear wiper would stop immediately and the front wipers would not come back on if the car was in drive after you had turned them off. During the first incident I stopped to get gas and when I got in to leave the pumps my headlights would not come back on. I drove the two blocks to my house by the street lights. I know from the internet I'm not the only person to have this water leak in under the dash of a ford expedition of f-150. It is a miracle if no one has wreck in a sudden down pour.
