Hi all hoping for some help troubleshooting a electrical problem.

My indicator dashlight will flash once with just about any switch trigger. For example, pressing the brake, turning the headlights on, turning the airconditioner on etc. will all see the indicator dashlight flash once. I'm stumped!
The other issue which I suspect is related, is my trailer light flashes with the indicator despite there being no trailer attached.

So far, I've cleaned up the battery ground and the two grounds above the rear tail lights but that's seen no success.

Here's a video link:
Open to any ideas!

Cheers!

 

The trailer light will flash one when you first turn on you turn signals but only once. I would take a look at your trailer connector to see if it has been damaged or has bad corrosion. I had a 4 way converter fail on me and the trailer light would come on and stay on any time I used my blinker.
