Have you read about your HVAC system in the owner's manual? With everything set on "auto", the fan speed will vary from almost "high" speed to something very near minimum. Much of the fan speed is dependent on where you have your temp wheel set. The overhead light has a small grill where interior air is drawn in via the sampler motor, which sends the air to the temp sensor, which varies the fan speed.
There isn't a vacuum pod under the hood of the car. Use our search tool and look up "vacuum block distribution". The distribution block is behind the glove box/passenger airbag.
As for the fan delay at initial start - normal. In the winter months, the fan will not blow until the coolant temp is to a point that warm air comes from the vents..when keeping the system set to automatic.
