have checked bulbs, fuses, and changed the brake light switch. Still no brake lights. Any suggestions? Read something about bulb sensor, but can’t find location.
Have you checked the sockets? Have you checked the lighting units to ground?
This is a job for a multimeter. Start at the lighting units and find the missing voltage.
Check the switch at the brake pedal and make sure the connection to it is ok and also verify that power is getting to the switch by using a test light probe.
