Question about 2002 Ford F250 Super Duty SuperCab

1 Answer

'02 Ford F550 high beams won't work until truck interior warms up

Everything eletrical works, I've replaced turnsignal/bright light/wiper lever. This has been going on for over a year and the circumstances hasn't changed. Before I torn into steering column to check ribbon I wanted to find out what color wires are for low and high beams, and chase them to see if there's a pinched or bare wire. It seems that when the interior warms up that they may work, but they will go back out. That is the only reason I felt that it is isolated to the interior. Any help would be greatly appreciated, Thanks.

Sounds like your on the right path. The multifunction switch and connectors are a real good place to look. The terminals get heated up from poor contact and will melt the connector. Renew the switch and connector if you see a problem there. You can buy pigtail connectors at NAPA. Good Luck

Headlights dont work


There is a relay and 2 fuses for the head lights. When you pull the lever back the high beams come on so the low beam on both bulbs could be burned out not unusual.

Have a 91 Ford Explorer. Front headlights having issues. Good bulbs I believe. Sometimes when switching between high and low beams on the column, lights would go oput for a moment then back on....


Sounds like it has possibly got a defective multifunction switch,which is part of the turnsignal lever/high beam lever switch. Aside from physically diagnosing the circuit I would say replacing the multifunction switch may take care of your problem.


Hope this helps

My bright lights do not work on my 02 ford f150. Where would I begin to look for the problem?


When you say they do not work, is this with the MFS ( MultiFunction Switch ) pushed forward to bright, or with both the high ( MFS forward ) and FTP ( Flash To Pass, pulling back on the MFS lever ) ?

Did you check the fuse for the high beams ? ( Cab fuse panel, fuse # 16 ) with a meter or test light on both pins on the back of the fuse ? To have power on this fuse you need the main headlamp switch turned to the headlamp position, and the MFS pushed forward ( or holding the FTP function ).

If you have power on the fuse with the MFS forward, it would be a bulb issue ( burnt out ) , time to check the bulb connector for power when the high beams are on, this is the Light Green w/ Black stripe wire at the bulb connector.

Directions in your owners manual on getting to the bulb connector by removing the headlamp housing ( ie. changing the bulb ).

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

I have a 2004 ford taurus and my turnsignals dont work anymore. In the morning they will work a couple times but after that they dont work i checked all the fuses but someone told me i may need to change...


the multifunction switch is a common problem on fords. the switch controls the wipers, turn signals, high beams and hazards, and sometimes only 1 part of it will fail. in your case it sounds like 2 parts fail at the same time.

As for your dash lights, and electric locks, check your fuses. If the blue high beam light on your dash comes on, but the headlights don't get bright, your bulbs have burnt out, and need to be replaced. They probably went one at a time, but you didn't notice until the second one went. If the high beam indicator isn't coming on, it's probably your switch.
