The blinkers in the OEM mirrors are LEDs and the whole clear part of the cover is the light and will need to be replaced. Take the cover off and check it out. It is held to the back of the cover by 2 screws. Check the connection first.
i took off the glass, and took off the 2 small screws holding the led assembly to the mirror cover. but i can't figure out how the led comes out. it seems to be behind all the other mirror components (spring, frame, etc). how can i tell if it's bad or not? it has 2 wires going to it, but it doesn't blink.
The outer cover slides off. The LED part comes off to the inside. If the cover is still on the frame of the mirror, then everything in the mirror will be in the way. Fold the mirror back and pop the clip that holds the outer cover on and slide it off.
