I have had this problem a few times.
Turn Signal flashes quickly, replace the bulb, still flashes quickly
Swap bulbs right to left, still flashes quickly
Last time I fixed it by removing and resetting the flying lead to the turn signal light...that's not working this time...any suggestions?

The turn signals are driven by the BCM. When the BCM senses a failed bulb it goes into fast flash mode. The way it senses a failed bulb is by measuring the resistance of the circuit. One of the results of this is if the stock bulb is replaced with a lower resistance one, as in an LED replacement, the BCM incorrectly senses this as a failed bulb and goes into fast flash mode to alert the operator.

If you are getting the fast flash, check the continuity and verify that both bulbs on the offending side are fast flashing and one is not "out". If both bulbs are fast flashing, look at the resistance of the bulbs to verify that its the proper level.

Since the symptoms you are describing appear to be intermittent? it is possible that you have a good bulb but intermittant contact.

I was thinking the same thing. that always means you have a bulb out. Now, if you do have an LED or one with less resistance, I think there's a resistor you can install to cure that. Did you just buy the car? have you recently changed any bulbs? did it used to work normally? Please, more info.

LOL

All this is covered in my Punisher thread, including pictures of my backup LED compensating resistor mounting. :thumbs:

You had a resistor for LEDs in your backup lights? Really?
Yes, they are on a flasher and spider lights, so I figured what the heck
