Many cars use the same bulb for the brake and turn indicator. Seems like one is burnt out. Have someone step on the brake and see if one of the brake lights does not respond.
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
check fuses then check all the bulbs, then check the turn signal switch the brake lights work through it
Check the fuses and the bulbs.
Check the bulbs - they are doubloe filamented with the smaller being for brake/turn signals Check the fuses
check the fuses.
Check fuses and bulbs first.
check the brake light relay under the hood
Check the fuses first then check the bulbs.
How do you replace brake lights
check for a loose ground wire
the circuit boards on the taillights are bad.
Turn signals use a relay or 'flasher' which is usually located on or near the column under the dash. Brake lights get their power thru the brake light switch on or near your brake pedal under the dash; check it with a 12v circuit tester.
