Three problems related to exterior lighting have been reported for the 1997 Ford F-150. The most recently reported issues are listed below.
My interior and back exterior lights come on and go off randomly sometimes while driving on the roads. The light in the back above the truck bed is bothersome because it could cause attention of another driver causing a accident. My mother also has a Ford f150 that does the same, however her truck isn't the same year.
Lights do not work.
During warm weather the sensors in the door appear to be heat activated which does not allow the dome light circuit to close, when the door is opened the light comes on as it should but stays on when the door is closed, at night this causes visibility problems. Nlm.
