Left blinker going ape

[blue_healer_guy]

Got a left blinker blinking faster than a nick punto head first slide into first. Also, dome lights dont work. 2003 dodge dakota, any help?: Thanks.

Normally when it blinks too fast one of the bulbs are out. Check carefully, sometimes there is more than one bulb in a light, so even if it looks like its working it still may be only one of two bulbs working. Otherwise the most common thing I find is broken or corroded wires from a trailer plug installation.

Check dome light bulb and fuse.

Try the cheapest thing first. Throw in a new flasher.

since dome light doesn't work, sounds like there could be a short somewhere. That would make flasher go ape, right? Might have better luck in automotive forum.

thanks for the replies guys, havent had time to work on it yet, but now everything works fine. leading me to more of a short?.

A short will, or at least should blow a fuse.

Yes, you would think that. But a bad bulb or flasher wouldn't cure itself.

[Macgyver55]

A bad flasher would do the same thing on both sides, not just one or the other.

A bulb with a loose filament can and will work intermittently in many cases.

A corroded connection can often work intermittently with moisture involved.

Remove each bulb and clean the connections with steel wool or a small file and spread a thin layer of dielectric grease on all the connections. Remember to keep the bulb clean and do not touch the bulb directly with your fingers, also wipe the bulb with a Kleenex towel when done.

Those are good points, especially about the flasher. But doesn't a bad bulb make the flashing slower? It was my experience that a burned out bulb makes slower flashing. A trailer or other extra load makes faster flashing. That is why I suggested some sort of short.

Is there a trailer harness? They run under the car where they could get damaged.

Every car I've ever seen the flasher went faster when a bulb burnt out.
