Hey guys. I have a problem. I have a 1997 honda civic that my sister gave to me. The car has several problems but one problem i seem to cant find the solution is this. The front passenger side door only opens from the outside. Ppl have to always roll down the window to open it. When i open the door, I see the thee screws that surrounds the locking mechanism. But one is missing and the last two are so loose that when you close the door they slip out a little. Can I fix it myself or do i have to get the mechanic to fix it. I want to take my drivers test in it but i get docked points if the instructor cant open the door from the inside. Please help!
