Removal of the evaporator entails
extensive dismantling of the vehicle interior
in the area of the facia, drilling out structural
rivets and physically deforming the facia
structural panels. For this reason, removal
and refitting of the evaporator is considered
beyond the scope of the DIY enthusiast and
should be entrusted to a Vauxhall/Opel dealer.
