Connect a test light between connection MAN
and BPT3 of component 203.
Does the test light illuminate?
YES
Use a multimeter to check the presence of +
12 V on both connections 21E and 21C of
component 1512.
Is the feed approximately 12 V?
YES
Check for + 12 V using a multimeter between
connections 21K and BPT3 of component 203.
Is the feed approximately 12 V?
YES
Replace the electric window motor (see MR 412
bodywork, 51A, Side opening element
mechanisms, Front side door electric
window mechanism: Removal - Refitting).
NO
NO
NOContinuity fault on connection BPT3, pay
close attention to the intermediate
connectors. Check the continuity.
Otherwise the fault is caused by the wiring;
if there is a repair procedure (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the
wiring; if not, replace it.
AFTER REPAIRCheck that the electric windows are operating correctly; if not, run fault finding
