Hi, I have a 2007 grande with an indicator issue, all left side indicators including rear and front are not flicking when indicating, they light up but they are dull.
Anybody got an idea of what this could be, a wiring issue?
Thanks

Could indeed be a wiring fault..have you looked at the terminals in the light clusters?..sometime corrosion can cause this issue too..check/replace the bulbs too..sometimes the paint on the bulbs flakes off..I know off two cars that recently failed mots due to the paint flaking off the bulbs and they werent orange enough..I kid you not..

Bad / corroded connection, here's the drawing ...

Cheers, Bernie
