I’m new to this forum stuff. but this is my first car and i want to learn how to fix some of the problems myself. but i don’t know where to start??? i have a power steering leak, ac leak, oil leak (can’t stop there can it?) valve seals need replacement, sun roof motor is messed up, my passenger door does this clicking noise when i lock it, exhaust clamp broke so it loud right under me. front window has cracks? i don’t know where to start. my stepdad is more of the car dude, but i know how accepting some might be. i just want to learn. like where do i start
