Blower motor resistor and blower motor – replacement

Warning: The models covered by this manual are equipped with a Supplemental Restraint System (SRS), more commonly known as airbags. Always disarm the airbag system before working in the vicinity of any airbag system component to avoid the possibility of accidental deployment of the airbag, which could cause personal injury (see Chassis electrical system). Do not use a memory saving device to pre­serve the PCM’s memory when working on or near airbag system components.
