Hi I bought a used 2005 Sierra just over a year ago. I understand my question is a bit wordy lol(just tryin to give a full picture of the issue) please read through.
It's had annoying but minor electrical issues from day one. But now it's causing Inspection failure.
When no running or headlights are on, the directional work perfectly. For the last 6 month's, when the lights are on, even without turning the signal on, the left(and only the left) signal stays solid. And 2 or 3 of the Less on the side mirror stay out. The right side still works fine. I've changed the signal lever and the module with no change.
I might add, one of the original issues were when the lights were off the After market radio will be just static.. Turn the lights on and the radio works fine(hoping that helps diagnosis).
I'm a carpenter so no truck = no work
Thanks all for any suggestions
Roger
