1 quart every month

Toyota solara 2008. What do I need to take off I would like to clean the back of the plastic thanks

The sound system goes off about every 10-20 seconds for a second or two when I'm driving with the top up. When the top is down it has never gone out.

Can the factory tint be replaced without replacing the window. The tint film is bubbled restricting vision.

The sensors, I am told, were put in aftermarket. Both they and the defroster went out at the same time. Wiring or fuse problem perhaps?

need to know how to remove the cover to to determine the problem

Both issuses happened at the same time.
