45 problems related to electrical system have been reported for the 1999 Ford Expedition. The most recently reported issues are listed below.
While driving the vehicle stalled without warning. It was later determined that the vehicle spark plugs were defective.
Upon starting vehicle consumer smelt smoke from within the cabin. Consumer proceeded to turn the vehicle off, and lifted the hood. Engine compartment was on fire. Dealership was notified. Fire was extinguished, and vehicle was towed to dealer. An electrical problem caused the fire. Component that failed unknown. Vehicle was repaired, and returned to the consumer.
There is a problem with vehicle's electrical system. All doors lock/unlock intermittently without engagement. Also the vehicle's interior and exterior lights engage on/off. Ph.
The passenger side cylinder head needed to be replaced to the very common spark plug blow out. From other websites I have seen this to be a very common occurrence among Expedition owners. The repair cost was in the area of $1800. 00. Ford does not acknowledge this as a defect and yet it happens to people every day.
The interior lights would flicker on and off intermittently. The windsheild wipers would turn on and off intermittently. The radio would turn on and off without anybody touching the controls. Truck switches into 4x4 mode when driven thru car wash. I could have neglected to fix the problem, but, decided to have necessary repairs done to the 1999 Ford Expedition at a cost of almost $2000 to me. . . . . My extended warranty did not cover the necessary repairs. . . . . . . And Ford (the manufacturer), would not help either. I had 2" gem modules" replaced in this vehicle within 1 and 2 years. The second time Ford/Ford dealer replaced the gem module. The vehicle still switches into 4x4 after going through a "drive thru" car wash. . . . . . Water must be causing an electrical problem somewhere underneath the truck??????? the first gem module is available----I paid for it, so I kept it. . . . . Brookdalke Ford (dealership), said there was water damage to the printed circuit board which is what the gem module is made up of. . . . . . . There is no visible water damage to this part. I work for an electronics manufacturer. . . . . . And a few of our technicians agreed ---no water damage. . . . . . . It's a design problem by the manufacturer or the designer. . . . . . .

Windshield wipers intermittently wipe without switch being activated, rear wipers fail to wipe at all.
Vehicle continually experiences a no start/turn over condition, consumer can jump the vehicle with cables and it is fine, this situation happens speratically, dealer does not know what the problem is, they have replaced the module, however it still continues.
Experiencing intermittent problem with all exterior lights going out on two occasions. Dealer notified.
