The circuit consists of the pcm the wiring and the vent solenoid itself. If you have a trouble code setting which says there is a circuit fault, it means that there is a problem with something in the circuit. The most likely culprit is the vent solenoid which should be in the left rear of the vehicle behind the wheel opening shield. The next most likely culprit would be a broken or corroded wire between the computer, and the vent solenoid.
