general problems of the 1998 Ford Ranger

My fuse #27 for backup lights and the o/d keeps blowing out and now the o/d light flashes sometimes I pulled the cover off of the steering column but the o/d cord wasn't pinched or damaged also no appearance of any wire touching anything.

Upon activating turn signal on a dark morning, the headlights completely failed. Activating the dim/bright lever provided intermittent activation. Upon release of the dim/bright function the headlights would not remain on in either dim or bright mode. Other users of vehicle report complete headlight failure. They too have been able to restore headlight function intermittently after several frantic seconds operating the light switch or the dimming lever while traveling in the dark.

Parked out on the street in front of my house, caught on fire around 9 pm. Fire trucks came and put it out and knocked on the door around 9:25 pm.

Turn signals failure at times, does not happen all the time.

Door ajar switch malfunctions; causes dome light to stay illuminated; had to replace switch inside door assembly.

While driving with headlights on at night, the headlights suddenly went out. The consumer had to turn the headlight switch several times to get the headlights to operate again. The lights went out again and the consumer had to move the switch on the steering column back and forth to get the lights back on. The consumer was aware of other owners who have experienced this same problem.

While driving with headlights on at night the headlights go out intermittently. The consumer must turn the headlight switch several times to get the headlights to operate again. When the consumer placed the high beams on, they would fail to go back to dim. The switch on the dash sometimes failed to bring the lights on, would take several minutes before going off. The switches in the doors were faulty and casued the lights to fail to turn off.

While consumer is driving the vehicle suddenly looses power, consumer has taken the vehicle to dealer many times but the are unable to diagnose the problem and the computer says there is nothing wrong with the vehicle. Nlm.
