Hello,
It sounds like you have an instrument cluster that is shorting out but to be sure lets unplug the cluster to see if the problem stops. Here is the blinker and emergency flasher wiring diagrams so you can see how the system works. There is no flasher just front and rear modules.
Check out the diagrams (Below)
Please let us know what you find. We are interested to see what it is.
Cheers, Ken
