BRAKE LIGHTS NOT WORKING BULBS ARE ALL GOOD NOT ...
1989 MAZDA 323
Brake lights not working, bulbs are all good, not sure how to test the brake switch under the brake pedal. Fuses are all fine

Disconnect the brake switch wiring connector and jumper it-light comes on-adjust the switch or replace it-

How many wires are on the switch? One will have 12 volts all the time. If there's only two wires jump them together with a stretched-out paper clip or piece of wire. If the lights turn on, replace the switch. If they do not, and you have voltage on one wire, suspect the turn signal switch. The signal switch is in the circuit if the bulbs do both functions, signals and brakes. If you have yellow rear signal bulbs the brakes and signals use different circuits.

The WHt/BLU wire on the stop light switch should have power (12V) on it at all times with th ignition swtch ON (the ORG/RED wire should not have power at this time). If the ORG/RED wire have power to it now the stoplight switch needs to be adjusted (it is set to keep the brake lights on all of the time---this is not your case, however).
Once the brake pedal is applied the ORN/RED wire on the stop light switch should have 12v. If so, switch is working. If not, make sure that the brake pedal moves completely away from he switch when the pedal is applied, if not adjust the stoplight switch.
