Headlight problem 2005 Crown Vic - Which Relay?
I have a 2005 Vrown Vic P71 with low beam headlights intermittently not turning on, or turning off while on. I've determiined that the problem is most likely one of the 4 relays in the upper PCB of the Lighting control module. When my headlights do not turn on, a tap on the module will turn them on. However, I find it odd that I hear the relay kick in when I tap on the module. If the relay were bad, I would suspect poor relay contacts, not a stuck relay contact mechanism. The solder joints on PCB look good. I don't think the problem is a cold solder joint. If anyone could describe which relay is for the low beams or can provide a pic pointing out the correct relay, that would be great!
