Answer: Its not a simple job to power windows and locks. you can buy aftermarket door lock kits from many different retailers but usually unless you get them installed professionally the warrenty is void and they probably wont work properly. as for the power windows, you would be quicker and cheeper just to get a whole new door assembly. but make sure that the year of car you drive came with those options to begin with, or else your just wasting your time
Start by checking the fuse.
