Checking of heating pads

1. Undo the wire connection 67/93” (red and yellow
wires) from fuse 11. Connect a test lamp between the
wire connection and the fuse terminal.

2. Switch on the ignition.

3. Find the thermostat in the seat (feel with fingers) and
cool the area in a suitable manner, for example with
a cooling spray of the same type used for radio and
TV service.

COOLING THE THERMOSTAT

After a while the thermostat will cut in and the lamp
should light.

If the lamp does not light it may be due to:

Faulty fuse

Wire fracture in the wiring or the heating pads

Faulty thermostat

Faulty grounding

Defective test lamp

Possible wiring fracture in heating pads, check with the
aid of a buzzer

(Disassembled, heated seat)

A. Backrest heating pad

Connect one of the leads of the buzzer to the pad leads
(the splicing sleeve is pushed into the PVC tube). If there
is no fault in the wiring, the buzzer will sound when its

other lead is connected to one of the two pins in the
dual-pole splice cover.

Dec. 1975

CHECKING WITH A BUZZER

B. Seat heating pad

Cool the thermostat until it is below the cut-in tempera-
ture and connect the buzzer as under A but to the other
pin in the dual-pole splice cover. Note that even a ther-
mostat fault can mean that the buzzer will not sound in
this case.

Changing the heating pads

1. Take out the seat.

2. Remove the seat upholstery. The backrest cover can
be removed when the zip at the bottom has been
opened. The seat cover is removed by undoing all the
lower clips, the rib on the right-hand side of the seat
and the base rib. Pull up the cover from the right, and
tuck it out of the way so that the heating pad is acces-
sible.

3. Remove the heating pad(s). Dissolve the glue with
pure gasoline (cleaning gasoline) so as not to tear off
large pieces of the foam rubber cushioning.

4. Glue on the new heating pad(s) with suitable impact
adhesive such as Bostik A3. Connect the wiring so
that the pads are in series.

5. Replace the upholstery and mount the seat.

Changing the thermostat

Remove the seat cover, see points 1—2 ‘Changing the
heating pads’. Remove the binding threads from the
thermostat connection wires, after which the thermo-
stat can be pulled out and replaced. Fit binding threads
to the new thermostat to eliminate the risk of the wires
working loose after a time.

Back seat

The back seat cushion and backrest are of spring interior
construction with upholstery and covers. The cushion has
a plywood base, while the backrest has a backing of pressed
sheet steel. The cushion is attached to the body by two
hinges at the front edge, while the backrest pivots on two
hinges at the bottom. In the upright position, the back-
rest is secured by a catch so that it cannot be forced for-
ward by loose objects in the trunk compartment if the
brakes are applied hard.

The trunk can be extended into a larger cargo compart-
ment at need by the following rearrangement of the back
seat cushion and backrest:

Press up the catch lever of the rear seat cushion and raise

the front edge of it, then pull it forward and downward
to stand the cushion on edge behind the front seats. As

from chassis No. 99.008.118 a catch must be released
before the seat cushion can be raised. The catch lever is
placed below in the edge of the cushion. On the 4-door
model the catch is released by pulling the control to the
right under the cushion. Next release the backrest catch
and fold the backrest forward and down.

Instrument panel as from 1971 model

As from the model 1971, the instrument panel is com-
posed of several parts. The top consists of two safety
pads with a tidy box mounted between them. The lower
part is made up of a three-part switch panel and a knee
guard mounted along the bottom edge of the switch
panel. The knee guard also incorporates a courtesy handle
located under the glove compartment.

The center section of the switch panel can be removed
