On a car they do that when a bulb is bad, or the flasher could be bad.Hi,
Last 2 days my left front,rear,dashboard turn indicator stays on soon as I turn ignition on. I'm driving like that. Sometime goes off and operates normaly. Right turn signal indicator works perfect. When I turn left one on I do hear a relay clicing and slightly iluminates a litle bit brigter for half a second. where I start?
