Need to check the brake safety switch as no noise happens

Customer Question

need to check the brake safety switch as no noise happens when I turn the key. Confirmed battery is fine, alarm company rep helped me test the ignition bypass on the alarm, it is fine. Next step is the brake safety switch.
JA: Is the car in "Park" or "Neutral?" Do you know if your car has a "wheel lock" feature?
Customer: park and does have steering wheel lock. 2007 Pontiac Vibe.
JA: Are you fixing your Vibe yourself? What have you tried so far?
Customer: I am trying to fix it here in my driveway as it wont' start. Confirmed battery is fine by using jumper cables, alarm company rep helped me test the ignition bypass on the alarm, it is fine. Disconnected and reconnected a small back wire with clip on solenoid. seems fine. Next step is the brake safety switch,.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Steering wheel moves freely, no noise at all when I turn the key. I saw there is a unit connected to the brake pedal that activates a switch when the brake is depressed.

The brake shift interlock is for shifting out of park when you press on the brake pedal, why do you want to test that if when you turn the key to start the starter will not crank?

Here is the wiring diagram, check those fuses for voltage with a voltmeter or 12 volt test light on both sides of the fuses and if they are ok,let me know.

Customer: replied 10 months ago.
There is a fuse panel on the driver's side, under the hood, next to the air cleaner. Based on the info inside the lid, the fuse for the starter is a 30amp MAIN.
Customer: replied 10 months ago.
I have a new volt meter that has a Resistance function. Not sure if I am using it correctly.
Expert:  Mike S. replied 10 months ago.

There is also an "am2" fuse in the instrument panel fuse block.

Customer: replied 10 months ago.
There is not. There is a 5amp Alt-S. All the fuses test the same resistance. No fuse issues apparent.
