Blinker Help!

[Cam-Shaft]

Hi All,

Not to good at wiring and need some help with my 69 K10.

Headlights (high/low), center markers, front blinkers, taillights, and brake lights all work. Hazards work great as does the front blinkers.


Here's the issue. The ignition is on, I hear the blinker click and the rear blinkers both blink simultaneously. When flasher switch is in the right blinker position, front right blinker turns on and both rear blinkers are still flashing. When flasher switch is in the left position, the rear right blinker turns off but the left front/right blinkers function as they should. When brake lights are on, the flasher in the right position turns the arrow on the dash solid.

However, when the plug going to the rear lights are unplugged, the front functions exactly as it should!

I'm assuming something is messed up with the rear wiring, anyone have any ideas as to where to start?

Thanks in advance!
