01 f-150 Lariat. The running lights are working but the turning and brake light on passenger side not working. Suggestions!
First check the bulb sockets with a meter while the turning light is engaged. If no power is present use a small point probe to pierce the insulation on the wires and see if power is present. If it is, then the connection between the wire and the socket is probably corroded, or the contact points holding the bulb corroded. Replacement sockets are available at most auto stores.
