peugeot electric windows 306

hi
i have peug 306 k reg 82 think and the electric windows r a nite-mare.
they work only sometimes and recently the pasenger side went down and
cannot get it back up again , took door panel off can see the wire for the
switch but stuck from there dont no where the fuse box is or where the
wires go. please help, can someone advise is there a easy solution for
this or do i have t take to a garage- car not worth that much, just want
me windows to go up!!!!!!!

 

if it's the motor goto german, swedish & french and buy one for £50. Pug
charge £100.
is the window wire okay. ours tangled itself up on the spool it runs onto.
