someone hit my side mirror housing on 97 E420. the mirror is still attached strongly to the car but it flaps around both ways quite easily. upon observation i noticed that there is a spring in the middle, it's still hooked to the car but it doesn't grab until i pull the mirror away. this is probably why it's so loose.

is there a way to fix this diy?
