A little more information is needed. So if I read correctly the external lights flash correctly but the indicators on the dash both flash? Interesting.

The only commonality I can see is that the dash indicator lights are coupled with the front signal lamps at a junction box W-BL(rh) & G-W (lh) wires. Are you sure both front lamps are not blinking together?

I’ll post the schematic

If I understand you correctly the outside turn indicators (front and back) are working as they should, but both of the pilot lights on the dash are flashing together.


Looking at the wiring diagram, are you sure that both front outside indicators and both pilot lights on the dash aren't flashing together? Since the green/white and white/blue wires are next to each other in the junction block at the base of the steering column, I would inspect the wiring at the junction block the base of the steering column to see if those wires are shorted together.




I also attached an interesting article from the March/April 2016 Early Bird magazine that explains how the turn indicator switch works.

I had this same thing happen. Replaced the flasher and that fixed it.
