My brake lights quit working. Replaced the brake light switch, didn’t help. Checked the connector and wasn’t getting power.

If it isn't getting power there is a 20 amp Stop Lamp fuse in the under hood fuse box, Use a test light and see if it is blown. It powers both the CHMSL and the lower brake lamps. A quick test would be to turn on the hazard lamps, they are powered through a different fuse. If they work normally then it could be the fuse or the wiring under the box, which is a common failure item as they corrode easily.
