could anyone help me solve a few problems with my car.... i drive a mk 5 fiesta zetec s, but recently the electric windows, hot and cold air blowers, have stopped working, also my indicators dont flash either, i have changed the flasher box and checked the fuses many times, could anyone help me with this problem

 

Best start by getting a wiring diagram, then you can see if there is any one thing that powers all these things, could be anything from dodgy connection to broken wire, but you've done the obvious, it's worth the dosh for a haynes manual for the wiring diagram alone.
