SN95 Mustang RH Door Jam Switch
When your 1999-2004 Mustang has a faulty dome light switch several symptoms can occur. The first case is that the dome light doesn't come on at all, the second is that the dome light stays on all the time, and the third is that it can cause your remote door locks to malfunction.
Don't mess around with these annoying dome light issues, replace the dome light switch with this brand new piece from Ford. This push-button switch mounts in the front door jamb area near the door hinge.
