When the glass is raised, it then lowers automatically.
Probable cause
If the sliding resistance is too large when the glass is being raised, it is judged that
something is jammed in the window, and the window is lowered by approximately
150 mm.Incorrect window glass adjustment
Glass slider is incorrectly installed or warped

Does the glass move in the opposite direction when the power
window drive current is above the following value? (Refer to
P.42-30.)
Drive current:
Adjust or replace the power window. (Refer to P.42-29.)
NO
Driver's side: Replace the power window main switch.
Passenger's side: Replace the power window sub-switch.
Inspection Procedure 7

window.
Probable cause
The safety mechanism is released under the following conditions, and the window
will not be lowered even if something becomes jammed in it.
If the limit switch is always off
If there is an open circuit in the harness between the limit switch and the power
window main switch or the power window sub-switch

A-8 Noise sometimes appears on FM during travelling.
Does the problem clear up when retuned?Ye sOK
No
Does the problem appear only in certain locations and only with
certain stations?Ye sDue to electrical field conditions. (Multipath noise*, fading noise*).
Are connectors properly connected?NoCheck connector connections.
Ye s
Does noise appear when the radio switch is turned on while the
vehicle is stopped and the radio is struck while tuned away from
a station?NoStatic electricity noise:
Body static electric from the shock absorber rubber bushings used
to prevent vibration, tyres, etc. occurs because of separation from
the earth, causing a buzzing noise. Since no measures can be
taken on the radio side, other steps should be taken to discharge
the static electricity of the vehicle body.
Ye s
Is the radio body correctly earthed? (Is the mounting screw tightened
securely?)NoTighten the screw securely.
Ye s
Is the antenna correctly earthed? (If noise appears when the antenna
is moved, this means the earth is not securely connected.)NoIf rust is present at the antenna earth screw, clean and tighten
the earth securely.
Ye s
Repair or replace radio.
No
* About multipath noise and fading noise
Because the frequency of FM waves is
extremely high, it is highly susceptible to effects
from geological formations and buildings.
These effects disrupt the broadcast signal and
obstruct reception in several ways.
Multipath noise
This describes the echo that occurs when
the broadcast signal is reflected by a largeobstruction and enters the receiver with
a slight time delay relative to the direct
signal (repetitious buzzing).
Fading noise
This is a buzzing noise that occurs when
the broadcast beam is disrupted by
obstructing objects and the signal strength
fluctuates intricately within a narrow range.
CHASSIS ELECTRICAL ± Radio and Tape Player54-70
A-9 Ever-present noise.
Noise is often created by the following factors, and
often the radio is OK when it is checked individually.
Travelling conditions of the vehicle
Terrain of area travelled through
Surrounding buildings
Signal conditions
Time periodFor this reason, if there are still problems with noise
even after the measures described in steps A-1
to A-8 have been taken, get information on the
factors listed above as well as determining whether
the problem occurs with AM or FM, the station
names, frequencies, etc., and contact a service
centre.
