wiring circuit for N/S window winding motor

Hi,my first post, hope someone can help. I've just rectified a seized up
motor in the door of my Honda Civic 3 dr 1.4 P reg. From an external
source the motor will operate, in both directions perfectly, but with all
door connections made it will not operate. I have a feed (to) the motor
from both door switches and through the windings to a cable Blu/Red that I
cannot trace, it doesn't go to earth because it's live when the motor
changes rotation. A wiring circuit would be a great help or maybe someone
has had this problem themselves. appreciate any suggestions, thanks. Roy
