I searched for the solutions but didn't find it so I am asking here.

The plastic ring under the spring that keep tension on the swivel of the flag mirror broke so I tighten the cone bolt but seems not enough to take up the slack. Any idea on what I can do to keep the mirror snug ?

Trying to get my power door lock to work since I bought the car. When I plug in the power to the driver door actuator, it keep running non stop. Is this because the sensor is not aligned or actuator going bad? TIA.
