Check the connections if you think something came loose. Also trace the wires back to the plug and use a multi-meter to check and make sure you have you have power to the mirror and that your ground is grounded. I know that with my mirror if I move the slider to the right to cut the auto-headlamps on the green light will come on. If yours is like mine that would proally be the easiest way to check for power and ground.

When the green light is on it means that your auto-headlight are on. For the green light to come on the mirror needs a switched power and ground source. So if the green light comes on then the mirror is wired correct and the sensors in the mirror its self is broke and you need a new one. I don't have the auto-headlight feature hooked up so I keep mine off all the time.

The only wires that need to be connected for the auto-dimming mirror to function are the accessory (key on) power and ground connections. The rest of the wires (if any) are necessary for the auto-headlamps feature (if your mirror has that feature).

In your initial message, you indicated that you checked the wiring and it was right; if that's the case, then the auto-dimming function in your mirror is broken, or you didn't check your wiring carefully enough.

Using your DMM, connect the black (ground) lead to the ground wire going to the mirror, and connect the red (+) lead to the accessory power (I think it's orange/green) wire going to the mirror, and turn your ignition key to the "Run" position. Your DMM should read approximately 13.8 volts if that circuit is wired correctly. If it doesn't, then there's a wiring problem.
