At least 2 questions

How do i remove the headlight wipers? one is broken and currently put under the headlight so it wont scratch the headlight.

And are my rear door cards cooked? or any way to fix them? I know there are supposed to be some plastic thing in there but i have no idea where.

Also how do i access the blinker relay that makes the clicky sound? sometimes it makes a screech before resuming normal action.
