I am going to replace my door mirror Drivers Door mirror assembly because the actuator has stopped working the power does not work in it sometimes it comes and goes.
first I will test to make sure that there is power going to the plugs but assuming that may not be the issues once
I get the door paneling interior apart are there any other pieces I need to know about taking out to get the mirror assembly off and replace?
What Size sockets do I need to have a deep well socket I don't want to have any surprises once I get the interior door paneling out and then realize I cant complete the job without other parts needed.

thank you
