one of your left indicators(front or back) may have a loose connection with the bulb. Check these as one globe "out" will make the other link erraticly. This is to let you know that one globe is out or has a bad connection
Why would you want the blinker faster. They should blink at factory specs.
my 2000 Chevy Van's left turn signal is clicking erratically. What should I do? Check your indicator light bulbs as one may be out. There could be an earthing problem if not the bulb.
That's usually an indication of a burned out bulb.
turn signal relay fuse
If your blinker is blinking at a faster rate than normal, it usually means that one of the bulbs is out. For example, if the left turn signal blinks faster than usual, check either the front or the rear left turn signal. If both turn signals seem okay, check the front left parking light. (this is the front orange light that is on when your headlights are on)
your rear bulb is blown - replace the bulb The turn signal blinks fast because the bulb is going out. That is also why the others dont blink.
The trun signal lever needs to be replaced.
turn signal relay is bad
Buy a "highway" turn signal flasher
Check your bulbs and your flasher.
Probably needs a fuse.
This may very well be a problem with your ground connections at that turn signal.
