Electric window regulators, Convertible
251
Operation
The window regulators in the car can be operated by
means of switches in the centre console between the
front seats.
The supply is taken from fuse 11, via 29-pole white
connector 152A, to the following switches:
@ 162 (left-hand door)
@ 163 (right-hand door)
The following switches are supplied from fuse 2
(1988 model) or fuse 3 (1987 model), via 29-pole
white connector 152A:
@ 190 (left-hand side window)
@ 191 (right-hand side window)
To open the window, press the window symbol on the
button.
As an example, if switch 190 (for the left-hand rear
door) is depressed, one of the two pairs of contacts
(depending on whether the window is to be raised or
lowered) will close. Current will then flow to regulator
motor 193. It then flows through the second pair of
contacts of the switch, and to earth (117).
For a complete description of the wiring for the light-
ing of the switches on cars for the US, CA and JP
markets, see also the section entitled "Lighting for
controls, US, CA, JP”.
The connectors (59) marked SE, Fl, EU, GB, ME, FE
and AU in the diagram are used for adjusting the
operation of the system to suit RHD or LHD cars.
Automatic window regulator controls
Unlike the other switches, driver’s door switch 162
has two positions for lowering the window. This
switch is also connected to time-delay relay 287.
Position 1: The window travels downwards as long as
the switch is kept depressed in this position.
Apositive voltage is supplied to motor 164 across pin
2 on the switch and across the relay contacts. The
motor will stop when the switch is released.
Position 2: The window opens fully even if the switch
is released after a brief instant.
The coil of relay 287 is now supplied with a positive
voltage across pin 5 of the switch, and the relay is
energised. The motor is supplied across the closed
relay contacts (pin 15). The supply is maintained (for
approx. 6 seconds) by the time-delay function of the
relay until the window has been lowered fully, even if
the switch is released immediately. (The downward
travel of the window may be interrupted by setting the
switch to position 3, ”Raise”.)
Position 3: The window will travel upwards as long as
the switch is held depressed in this position.
The motor is supplied across pin 7 on the switch and
the direction of rotation is reversed, causing the win-
dow to be raised.
Fault-tracing hints
The electric window regulators will be operative when
the ignition switch is in the drive position.
1. Check fuse 11 and fuse 2 or 3:andcheck that the
supply to them is live.
2. Check that terminals 3 and 6 of the switches in
the centre console areiive. (On 162, terminal 3
only.)
3. Check the switches by measuring at their termi-
nals.
4. Check the connectors, cable harnesses and
earth connections.
Automatic window regulator controls
Check the automatic window regulator controls as
follows: Set switch 162 to position 2 and check that
the supply to pin 4 on the relay is live. Pin 1 should be
earthed. Check that pin 3 and pin 15 on the relay are
live.

Electrically operated rear-view mirrors
299
Operation
Each of the outer rear-view mirrors is operated by
means of a four-position switch.
The two switches 124 (left) and 125 (right) are sup-
plied from fuse 8, via 29-pole red connector 152B.
Each rear-view mirror will turn in the direction in
which the switch lever is moved. For horizontal set-
ting, only the mirror motors are used. For vertical
setting, a solenoid is also energised, which causes
the motors to move the mirrors vertically instead of
horizontally.
The following table lists the cables that are live/
earthed in each switch position:
Left-hand switch 124 and motor 126

1988 model for the US and CA markets
Cars for these markets are equipped with electri-
cally-heated rear-view mirrors 207, which are sup-
plied via the switch for the heating of the rear window.
Fault-tracing hints
The rear-view mirrors will be operative when the igni-
tion switch is in the drive position.
1. Check fuse 8 and check that the supply to it is
live.
2. Check that the supply to the corresponding
switch is live.
3. Byoperating the switch, check that the supply to
the corresponding motor and to the solenoid is
live. The table shown in the "Operation” section
lists the cables that are live in each switch posi-
tion:
4. Check the connectors, cable harnesses and
earth connections.
