Electric windows - Fault finding chart
ALP 1 No electric window operation
Applies to:Driver and passenger electric windows
Left-hand drive vehicle
NOTESUse Wiring Diagram Technical Note, New Twingo.
Carry out the various checks with the battery charged and + after ignition feed
switched on.
Check that the fuses are sound.
Use a 21 W test light.
Remove the driver's window switch (see MR 411
mechanical systems, 87D, Electric windows -
Sunroof, driver's door front electric window
switch: Removal - Refitting) and disconnect its
connector.
Connect a test light between connection SPB3
and the earth MAM of component 1512. Pay
close attention to the intermediate connector.
Does the test light illuminate?
YES
Shunt connection SPB3 with 21A and MAM with
21B to lower the window (to raise the window
SPB3 with 21B and 21A with MAM), on the
connector of component 1512.
Does the window move?
YES
Replace the driver's window winder switch (see

earth.
Does the test light illuminate?
YES
Check that the earth MAM of
component 1512 is correctly mounted
on the chassis. If the earth is faulty,
