my 2007 mustang 4.0 v6 has electrical problem my head lights, map lights will flicker
All the time? or ?
Yes.. It don't matter if you driving or at idle.
This is the voltage regulator in your alternator doing this,change the alternator.
Would that make my car cut off at idle when I have ac on and the coolant fan come on??
Possible,alternator surging with all the draw on it.
Cool thank you.
You are welcome.
