My left turn signal works intermittently.When I say left turn signal, I mean front, side and back as well so when it does not work, all 3 does not light up.The hazard lights work OK though.I am trying to isolate the problem.It is not a problem with the signal stalk as if I press my alarm, if it does not work, the left turn signal will not "blink".Nothing wrong with the bulbs as it sometimes work.Checked the fuses and it's OK.So can it be a problem with the relay or is it something else.Anyone had this problem before ?Mine is an E36.Thanks.
