Question
hi ,
i have a c70 ,last week both passenger and driver seats stopped working,i checked the fuses,everything seems to be fine,what should i do? thanks
p.S:friend of mine asked if i could find the electrical diagram for the seats(he knows lot of things about electrical&electronics)
                              thank you,

Answer
the problem is a broken microswitch holder.these are located just inside the outer hinge area for the seat backs.tilt the seat and look up into the edge where ot hinges.there is a switch in here.you could just tie strap the switch shut.doing this will not let the fuction work where you lift the seat back and pull the handle the seat slides forward.
