Symptom Chart

Symptom	Possible Causes	Action
Window(s) inoperative	Fuse(s) Switch fault Front switch isolator fault Motor/Regulator fault Channel/Runner fault Cable fault Window circuit short circuit to ground, short circuit to power, open circuit, high resistance	Check the fuses. Check the suspect window operation from the individual door switch and from the driver door master switch (it is unlikely that both switches would fail at the same time, so if the window is inoperative from either switch, suspect a fault other than a switch). If the inoperative window is a rear unit, check the function of the isolator at the master switch. If the concern persists and a noise cannot be heard when operating the door window glass, Refer to Pinpoint Test B . Refer to the electrical circuit diagrams and test the window circuit for short circuit to ground, short circuit to power, open circuit, high resistance
Window(s) 'one-shot' function inoperative	Window motor initialization required	NOTE: Do not install a new door window regulator motor for this concern. If the battery has been disconnected, carry out the initialization procedure.
Heated rear window does not defrost	Heated rear window circuit short circuit to ground, open circuit, high resistance	Refer to the electrical circuit diagrams and test the heated rear window circuit for short circuit to ground, open circuit, high resistance
Window(s) noisy during operation	Channel/Runner fault Cable fault Motor/Regulator fault	NOTE: Door window glass retaining bracket adjustment procedure Refer to Pinpoint Test A .
Slow or partial window operation	Fuse Switch fault Relay fault Element fault Circuit fault	Refer to Pinpoint Test C .
Rear door window glass bounce back	Window motor initialization required (using the manufacturers approve diagnostic system)	NOTE: Do not install a new door window regulator motor for this concern. Using the manufacturer approved diagnostic system, perform the window initialization routine
Front door window glass bounce back	Window motor initialization required Channel/Runner fault	NOTE: Do not install a new door window regulator motor for this concern. Refer to Pinpoint Test D .
