i'm having trouble with the passenger side low beam headlight on my 2006 Mustang GT. the passenger side high beam works fine but the low beam takes spells where it doesn't work. i've replaced the bulb a few times being careful not to touch it and doesn't help. i tried replacing drivers side and passenger side bulbs at same time with same brand of bulbs and doesn't help. have replaced the plug on the passenger side. again, no help. sometimes the low beam will come on and glow and then it will go out as i'm looking at it. could this be fuse/relay related? i've been running my driving lights at night to help out, but i fear it's just a matter of time till i get pulled over by "da law". anyone else have this problem with the 05-09 Mustangs? thanks for all reads and replies!!

 

I'm thinking more like ground wire. The relay should effect both sides and is pretty much either on or off, working or not working, no in between.


Both my headlights went out but I have HIDs. I tried to trouble shoot but found no signal coming through the harness so I hooked my relay up to my fog lights and they work with the fog light switch. When I have time I will actually fix it proper but that is the way I did it for now. I suspect it's actually an SJB issue as my horn doesn't work and TPMS is acting up too.
