Window lift usual suspects?

with you on most points, though the switch does more than reverse voltage
polarity via the switch, or there would be no need for 2 separate sources
for 12V going into @ switch? Got you on the power going through 2 switches
for each window, drivers switch and local switch. Needed to get the window
up from down position, with swich only working in down direction. As door
panel was off, simply slid out the motor leads from the switch harness and
reversed and used the down action to raise the window. This also reversed
the motion of the drivers switch for the window. I'll crack the drivers
switch tomorrow and hope for the best. Now to get the Bose speaker repaired
while the doors apart!
