Electrical problem

after driver door window controlls used then passenger controls quit working sometimes both up and down stops but most time passngr. Side will work on dwn but not up. Swapped to new motor same results, swapped out switches same results checked switch voltage if working 1 way only that side of switch cks.7.2 vdc other side 0.0 vdc. Passenger controlls seem ok until driver controlls used then when problem starts it affect both drver & passngr controlls
