Six problems related to fuses and circuit breaker have been reported for the 1998 Ford F-150. The most recently reported issues are listed below.
At some point the cruise control on my 1998 Ford f150 pick-up stopped working. As I seldom use it I'm not sure how long it was out. Next the #13 fuse failed. The replacement fuse failed immediately. With this fault I was unable to get the truck out of park if started in park. The abs light was flashing and the brake lights did not work. Took truck to earnhardt's Ford dealer for repairs. They traced problem to shorted brake pressure safety switch and speed control servo. Due to the defective brake switch the wiring harness was saturated with brake fluid. All three defective parts were replaced. These repairs cost $3,100 dollars. The mechanic (ken tueffel) stated I was very fortunate the truck did not catch fire. With the recent news reports on the Ford pick-up cruise control brake pressure switch causing fires I believe Ford motor company has known about the safety hazard of these switches for years and owe me a refund on these repairs.
An under hood fire occurred after the vehicle sat for 10 hours. Fire department extinguished the fire, and indicated that it originated within the fuse box.
Fuse box getting wet. Resulting in malfunction of all electrical componets. Ie lights flashing off, speedometer not working, 4x4 kicking in and out, ect.
Purchased f150 in June 1998. 8/98 had minior electrical problem - fan would not shut off when key turned off. In 9/98 lost speedometer, tachometer, could hear relays clicking. 10/98 replaced main fuse box due to arching between ternminals. 1/99 lost speedometer/tachometer/4 wheel drive switch, could hear relays in dash again. 1/99 replaced main switch box again due to arching between ternminals. 3/99 ocassional problem with windshield washer switch. They had no idea what caused the problem, if it was resolved, etc, but indicated the normal supply channel was out of the part.
Fuse for running light circuit failed.
There is a malfunction in wiring harness in steering column, when the tilt is used. This malfunction causes brake lights and turn signals not to work. Dealer has seen vehicle 6 times, and was not able to fix it. The dealer fixed only the harness but it failed again. The brake light and turn signal are still inoperable.
