Oftentimes, the motor is blamed when the wiring is the culprit. A good VOM
helps. Most trouble is at master
switch. Try holding passenger switch up or down while Master switch is
operated. Next, remove passenger side kick panel, and see if power is
present at snap connector that leads from master switch. Power = motor
suspect, no power, = bad
master switch, or wiring. No power ? Remove driver's side door panel
to access switch, pay attention to wiring that passes through door.
Oftentimes a kink leads to a break, but upon quick exam, looks OK. NO Power
at plug, run jumpers
to " male " connector that supplies power to window. hook jumpers to battery
and try passenger side switch. Power at plug ?
remove passenger side door panel, test plug that goes to motor for voltage.
Voltage = bad motor, no voltage = bad
wiring where passenger door wires pass through. That should about do it.
One caution, read up on servicing procedure,
some cars can be dangerous [ have springs ] that bite when component is
unbolted, keep fingers away when jumpering motor !
