- F150 4X4 4.6L DRIVER SIDE WINDOW SWITCH NOT WORKING, ALSO RUNNING LIGHTS STAY ON UNTIL I DISCONNECT THE BATTERY POST. LEFT HEADLIGHT ONLY WORKS ON BRIGHT BEAM

1998 Ford F-150 • 161,000 miles

Drivers window switch quit working today, along with the left headlight only working on brights. Marker lights will not shut off, I disconnect the battery post. There was two blown fuses under the hood, 15a and 20a which i'm not sure what they go to but I changed them.

You have a short somewhere. I am giving you the wiring diagrams for the power windows and the headlights circuits.
Check all the grounds for each and find if they share any common areas where a short form exposed wires could cause a short. It sounds like the foglamp relay might have gotten toated as well so it may need replacement.
