I am trying to familiarize myself with all of the controls and switches to figure out what is working and what is not. If not, I am open to any ideas available

1. The head rests on the front seat will move up with the motor but need pressure to go down.

2. On the dashboard there are buttons above the climate control that I can't come up with a purpose for and don't seem to activate anything and the symbols are not familiar.

3. On the right side of the sunroof track there is a small arm that has dislodged from the main track and may be broken. Where do I start with repairing it? Do I need to remove the sunroof itself?

4. Is there a place where I can find basic info such as that the kind found in the owners manual?

Thanks, more questions to come
