Alyssa203 are you 100% certain "it is constantly running even when car is off" as you described?
Asking because there is no fuse, instead it's driven directly from the Climate Control Module in the console (HVAC) If you turn the A/C off (Lower LH button) or open a door with the ignition key removed, the little fan should stop. If not it could be a faulty Climate Control Module (HVAC - expensive)
There is a YT video about the Aspirator, you can see the wiring details starting at 2:19
The Aspirator P/N is GM 22834330, it's cheap and can sometimes just be repaired.
Hope these comments help you and if so please let us know.
