equipped - see Chapter 11) the center panel and the center ventilator
grille and duct (see illustration lO.la). On 1988 and later models, it may
be necessary to remove the glove box for access to the blower motor (see
illustration lO.lb).
3 Unplug the motor electrical connector(s).
4 Remove the three bolts attaching the motor to the heater assembly,
then lift out the motor and fan (see illustration).
