SYMPTOM AND CAUSE OF SYSTEM MALFUNCTION HINT: The following are descriptions of the characteristics of each system malfunction...
The windows can be opened/closed by operating the power window
switches.
When driving with only one of the rear windows open, your ears might
experience a resonating sound. However, this does not indicate a problem. The
sound can be reduced by slightly opening a front window or by changing the
size of the rear window opening...
