Ford Fiesta (2011 year). Manual - part 30

Glass, Frames and Mechanisms – Overview

The function is based on that of the Fiesta 2002.25.

The main difference is the adoption of automatic
operation with anti-trap protection on the driver
side. To do this, the switch for the driver's door
window on the driver's door switch unit is designed
as a two-stage switch.

In addition, the window regulator motor on the
driver's door is provided with two Hall sensors. The
Hall sensors detect the speed of the window
regulator motor and therefore recognize any
obstruction as the window rises.

Description

Item

4-way switch unit

2-way switch unit

Rear window disable switch

In total there are six driver door switch units
available:

• Two 4-way switch units:

– one for LHD (left-hand drive),

– one for RHD (right-hand drive).

• Four 2-way switch units:

– one for LHD with three doors,

– one for LHD with five doors,

– one for RHD with three doors,

– one for RHD with five doors.

Because of the shape of the components, it is not
possible to mix up the switch units for LHD and
RHD vehicles.

NOTE:

• The 2-way switch units for the 3-door and the

5-door variants are identical on the outside.
They must not however be mixed up as the
software in the switch unit is matched to the
particular type of window and frame. The part
number suffix is used to determine which switch
unit is correct for the vehicle.

Switches - passenger door and rear
doors

E102753

These doors are equipped with a simple switch for
the window regulator motors.

This switch only has a simple up and down function
(no anti-trap protection).

Note:The window regulator motors in the rear
doors can be deactivated using the disable switch
in the driver's door switch unit.

NOTE: If a window regulator is operated at the
same time from the driver's door switch unit and
from the respective simple switch, the relevant
window stops immediately.

Each window regulator motor can be controlled
from the driver's door switch unit.

In addition, the motors for the passenger's door
and the rear doors (when equipped) can be
controlled using the corresponding simple switches
on the doors.

Service instructions

After the battery has been disconnected or the
driver's door switch unit has been changed, the
window regulator motor in the driver's door must
be reprogrammed (see current service literature).

Diagnostic Information

The switch unit and the window regulator motors
are not connected to the communication network.
The system cannot therefore be diagnosed using
the DLC (data link connector).

Instructions if there is a operating concern with
the driver's door window regulator motor:

• After the window regulator motors have been

deactivated, they continue to turn for a short
time. During "Ignition ON" the switch unit detects
the run-on phase via the Hall sensors.

• If however the ignition is switched off while the

driver's door window regulator motor is
operating, the power supply of the Hall sensors
is immediately interrupted. The run-on phase
of the window regulator motor then can no
longer be detected.

• In order to maintain the power supply for this

situation, the driver's door switch unit is
protected by an additional fuse F26 (in the
engine compartment fuse box).

• If the fuse fails the driver's door window

regulator motor will no longer operate.

Instruction if there is a malfunction of both front
window regulator motors:

• Both window regulator motors are protected in

common by fuse F25 (passenger compartment
fuse box).

Instruction if there is a malfunction of both rear
window regulator motors:

• Both window regulator motors are protected in

common by fuse F31 (passenger compartment
fuse box).

Component Tests

Heated Rear Window Switch

1. Remove the heated rear window switch.

2. Measure the resistance between pins 1 and 2

of the switch while operating the switch.

3. The resistance should be less than 5 ohms

when the switch is in the ON position and
greater than 10,000 ohms when in the OFF
position.

4. If the resistances are not as specified, INSTALL

a new heated rear window switch.

Rear Window Heater Relay

1. Remove the heated rear window relay.

2. Using a jumper wire, connect one end to

terminal 1 of the relay. Connect the other end
to ground.

3. Using a second jumper wire, connect one end

to terminal 2 of the relay.
