Having problems with your 2002 Ford F250 Super Duty SuperCab ?

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

\015 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.\015 Posted / edited by AnonymousUser on : 17-09-2018

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
