Fuses And Relays; Switches; Steering Column Switches; Lighting Switch Assembly - Opel Zafira B MPV 2006 Owners Workshop Manual

3.2 Access to the fuses in the luggage
compartment can be gained by opening
the stowage compartment cover
securely; if a wire terminal is being refitted,
use serrated washers between the terminal
and the bodyshell, to ensure a clean and
secure connection. When the connection is
remade, prevent the onset of corrosion in
the future by applying a coat of petroleum
jelly or silicone-based grease. Alternatively,
at regular intervals, spray on a proprietary
ignition sealer or a water-dispersant
lubricant.
Fuses
1 The main fuses are located behind the trim
panel on the left-hand side of the luggage
compartment, with additional fuses and relays
located in the fuse/relay box on the left-hand
side of the engine compartment
2 To gain access to the luggage compartment
fuses, turn the catches and open the cover
(see illustration).
3 To gain access to the engine compartment
fuses, release the catches using a small
screwdriver and lift off the fuse/relay box
cover (see illustration).
4 To remove a fuse, first switch off the circuit
concerned (or the ignition), then pull the fuse
out of its terminals using the plastic removal
tool provided (see illustration). The wire
within the fuse is clearly visible; if the fuse is
blown, it will be broken or melted.
5 Always renew a fuse with one of an identical
rating; never use a fuse with a different rating
from the original, nor substitute anything else.
Never renew a fuse more than once without
tracing the source of the trouble. The fuse
rating is stamped on top of the fuse; note
that the fuses are also colour-coded for easy
recognition.
6 If a new fuse blows immediately, find the
cause before renewing it again; a short to earth
as a result of faulty insulation is most likely.
Where a fuse protects more than one circuit,
try to isolate the defect by switching on each
circuit in turn (if possible) until the fuse blows
again. Always carry a supply of spare fuses of
each relevant rating on the vehicle, a spare of

lift
off the
fuse/relay box cover for access to the
engine compartment fuses
each rating should be clipped into the base of
the fuse/relay box.
Relays
7 Most of the relays are located in the fuse/
relay boxes in the luggage compartment and
engine compartment (see illustrations 3.2
and 3.3).
8 If a circuit or system controlled by a relay
develops a fault and the relay is suspect,
operate the system; if the relay is functioning,
it should be possible to hear it click as it is
energised. If this is the case, the fault lies
with the components or wiring of the system.
If the relay is not being energised, then either
the relay is not receiving a main supply or a
switching voltage, or the relay itself is faulty.
Testing is by the substitution of a known good
unit, but be careful; while some relays are
identical in appearance and in operation, others
look similar but perform different functions.
9 To renew a relay, first ensure that the ignition
switch is off. The relay can then simply be
pulled out from the socket and the new relay
pressed in.

Note: Disconnect the battery negative
terminal (refer to 'Disconnecting the battery'
in the Reference Chapter) before removing
any switch, and reconnect the terminal after

Steering column switches
2 The direction indicator and windscreen
wiper switches are an integral part of the
steering column electronics module, and
cannot be individually renewed.
3 To remove the steering column electronics
module, which also contains the airbag rotary
connector, proceed as described in Section 16.
Lighting switch assembly
4 With the light switch knob in the off position,
press the knob in and turn it to the AUTO
position (vehicles with automatic dipped beam
activation), or to the vertical position (sidelights
'on'). The switch assembly internal catch is
now unlocked and the switch assembly can be
withdrawn from the facia (see illustrations).
Once the switch is released, turn the switch off.
5 Release the locking catch and disconnect
the switch wiring connector.
6 Note that the switch assembly cannot be
dismantled; if any of its functions are faulty,
the complete assembly must be renewed.
7 Reconnect the wiring connector and push
the switch back into the facia.
Facia centre switches
8 The facia centre switches are contained in
the switch strip assembly located in the facia
centre panel. If an individual switch is faulty
the complete switch strip must be renewed.
