My mirror moves and operates fine but it doesn't dim at night when somebody has their brights or misaligned headlights aimed at me from behind. How many owners have failed auto-dimming rearview mirrors but live with it by simply pushing the switch up-down-left-right to avoid being blinded???
When the top is down I usually put up the rollbar to block some of the light: doesn't help much when I'm being tailed by a 4 X 4 monster truck
