I started my car yesteraday morning, turned on the headlights and noticed that the left side hesistated to come on for 1 second but eventually turned on. Right side is fine. I turned them both off, turn them back on again, the same thing happened. the left side slowly turned on after the right one is on(1 to 2 sec lack). Therefore I decided to leave them on since it was still a little dark. Got to work, turned them off. After work, turn them on and my left one doesn't come on at all. Put another 9006 bulb in, still the same.
Could this be a fuse? wires?
