can anyone tell me the proper way to get the passenger side window motor out? it has rivets that i'm not sure about removing. the glass is all the way down, and it is NOT wanting to move either. also, i have replaced the fuel filter, PCV valve, and other rubber lines, but still have a smell of gasoline. what can be causing it? put a new muffler and tailpipe on too. this little car runs great, but it seems to be a pain in the butt with minor stuff. Help please!
