Fifth Avenue V8-318 5.2L VIN R 4-bbl (1986)
Aspirator: Description and Operation
The aspirator is located on the rear surface of the blower motor housing. Pressurized air from the housing is fed through the air drive tube to the aspirator
and the evaporator-heater assembly. The air passing through the aspirator creates a slight vacuum which draws air from the passenger compartment
through the in-car sensor assembly.
