I'm about to own a converted honda fit GD pre-mmc and this will be my first car. I'm just 18 years old and newbie when it comes to cars.I have questions so I can maintain my car properly.Please help me TIA

1.The switch of wiper and signals are "baliktad" the wiper's switch should be on the right side and the signals' switch should be on the left.What should I buy? and how much

2.Driver's side side mirror I couldn't adjust the side mirror anymore so I couldn't see clearly.Can this be fixed?or should I buy another side mirror?

3.The gas pedal and brake pedal are too close to each other.Can I adjust these pedals? also the alignment of the gas pedal is too deep.Can I also adjust the gas pedal so it would be aligned with the brake pedal?

4."Naninilaw" yung headlights, what to do?

Still have questions but decided not to ask it today Please help.Sorry for my grammar. Thank you! God bless
