Toyota Sienna XLE Electrical Issue

#1

My headlights and dash illumination lights will intermittently flicker when I use the turn indicator to signal a right hand turn. Is it possible that there is a short in the turn indicator/high-low beam headlight control switch that is causing this?

Thanks for any replies.


#2

A most excellent prognosis!


#3

I wonder if there might be a bad chassis ground on the right side of the car at one of the sockets?


#4

I think you are most likely correct about the trouble being within the switch itself but it isn’t a short that is causing the trouble, it is due to an interruption of power to the lights.


#5

Thanks for the replies. If there were a bad chassis ground would it be logical to think the flicker should happen even without me using the turn indicator switch?


#6

Correct. If it’s only with the turn signal, it’s the switch itself.
