Almost 235,000 Vauxhall Zafira B models are being recalled for second safety checks to prevent fires starting in the fascia.
Examination of 2005-2014 models which have burned has shown a motor blower resistor and fuse could overheat and set fire to surrounding plastic fittings if an earlier fault was found and the unit repaired rather than replaced.
The work involves replacing the resistor, motor and pollen filter which may have developed the fault through poor windscreen sealing and water egress.
