If my 3rd brake light on my 2007 Jeep Commander is not working, could it be a fuse or loose connection or...?
could it be something other than the whole component.
A friend of mine who is an auto detailer thought it could be a loose wire or fuse or something.
Please let me know. It will save me $ 80 more or less
I have a voltmeter and have been using it to test my batteries and their recharger.
So, how do I test the wiring?
$80 and hour = $ 160,000 per year for a 2,000 work hour year. These mechanics are NOT worth that much

You test wiring by fixing the negative meter wire to a ground, like any unpainted metal attached to the chassis, and then touching the positive to any conductor you want to see if it is hot.
For example, the 3rd brake light has a plug. If it has 2 wires, you could just unplug it and put the meter across the 2 terminals. If there is only 1, then use the chassis ground for the meter negative.

There's a small module that works the middle brake light behind the left side wall cover in the rear. It's not a fuse because the same fuse works the other brake lights. It takes 5 minutes to learn to use a $15 voltmeter. If you can't bother to do that, get use to paying $80 an hour.

Probably not the fuse (or none of the brake lights would work). Could be a loose wire, a bad bulb, or a bad ground.

Why don't you do some electrical testing and find out instead of guessing?
