2000 F150 4x4 parking lights won't turn off until battery is disconnected.
The other night, I ran up to the store. When I arrived home, I turned off the truck and proceeded to go into the house. Before entering the house, I looked back towards the truck and the parking lights were on. All of the switches in the truck are turned off. Disconnectehd the battery and of course they went off.
However, upon reconnecting the battery, and testing to see if the problem can be dublicated.... it did. Once the headlights are turned on, the parking lights go on. When the headlights are turned off, the parking lights remain on.
Please help. I seriously don't feel like disconnecting my battery every time I have to use my headlights.
