Possible cause
Suggestion
Your box does not func-
tion and the fan impeller
which is visible from
outside does not rotate.
The cigarette lighter in
your vehicle does not
conduct any voltage.
In the most vehicles, the ignition switch
must be switched on, so that the cigarette
lighter has voltage.
The ignition is switched
on and the box does not
work.
Disconnect the plug
immediately from the
socket and execute the
following checks.
The socket of the ciga-
rette lighter is dirty.
This results in a poor
electrical contact.
Clean the socket of the cigarette lighter
with a non-metallic brush and a solvent, so
that the middle contact pin is clean. If your
cooling box plug becomes very warm in
the cigarette lighter box, either the socket
must be cleaned or the plug is possibly not
correctly assembled.
The fuse of the con-
necting cable is burnt
through.
Replace the fuse of the connecting cable
(5 A).
The vehicle fuse is
burnt through.
Replace the vehicle fuse of the cigarette
lighter (usually 15 A). (Observe the operat-
ing instructions in your motorcar for this).
