DIAGNOSIS
POWER WINDOWS
System With Only Front Power Windows, One or Both Windows
are Inoperative
CAUTION : When powering the window motors directly from a battery with jumper wires, make sure one of the
jumper wires contains a fuse. If the jumpers are accidentally touched together, the fuse will prevent sparking
and burns from sudden terminal heating.
