Cruise Control Vacuum Reservoir: Description and Operation
The vacuum reservoir is located in the engine compartment. It is made of plastic.
The reservoir stores engine vacuum. When engine vacuum drops, as in climbing a grade while driving, the reservoir supplies the vacuum needed to
maintain proper speed control operation. The vacuum reservoir cannot be repaired and must be replaced if faulty.
