Hey guys I’m new to the forum but I’ve been a long time subscriber!
So I’ve searched this thread for the problem I’m having and I don’t know if it has come up before or not but my girlfriend bought me a set of aftermarket tow mirrors that look OE for my 14 Sierra all Terrain sle. I installed them and they look great however after a day, I noticed when I put my turn signal on, all of the front turn signals would turn on ( left and right signals and both led signals on the mirrors). The rear signals worked fine.
They installed fine and didn’t require any wiring, the harness plugged right in and they worked fine when I first tested them. My factory mirrors were heated, power, power folding, red signal light, and puddle light. Just wondering if anyone has any ideas where I should start.
thanks!
