None of the brake lights are working on my 2006 mitsubishi galant. I changed both bulbs . I checked brake switch with an ohm meter. I checked all the fuses. Do the brake lights operate through one of the omron relays? If so, which one? If not, what else should i do?

It's either a bad switch or a wiring short. I'd bet on the switch. Disconnect the battery. remove the switch and test with an ohm meter.

its B R A K E lights...... replace ALL brake light bulbs at one time..DO NOT try any of them until you have finished ALL of them...your b r a k e light switch may be bad...

First check the bulb. If it looks good (or test good if you have an Ohm meter) then check the fuse for "interior lights."
If those look good, then you need to make sure you are getting power to the dome light connectors (using a voltmeter). If you have no power to the dome light, but everything else test out fine it is either your door switches, or interior light switch.

• For the tail light you first need to remove the brake light that is part of that assembly.
• Open the trunk.
• Inside of the trunk is some matting you need to pull down a bit.
• You may need to remove a net first.
• Once you pull the matting/carpet down you will see some plastic wing nuts around the are of the brake/tail light.
• Remove them.
• Now wiggle the brake light out
• Now wiggle the tail light out.
• Twist the socket to the bulb that is bad out.
• The bulb just pulls strait out.
• Revers to complete.

• Thank you for using FixYa.

you get a voltmeter and check the ohms reading from the brake sensor see if it still works correct or broken hope this helps

Bulbs are just like a fuse to for they blow out like a fuse. You have a brake light switch mounted near the brake pedal. Check that switch out with a OHM meter. Just unplug the switch and feed the Ohm meters contacts into the switch. Then push the brake pedal down to see if it completes the circuit. If a OL reading is showing at all times the switch is bad and needs to be replaced

did u check the bulbs?

it could be the electrical circuit or the fuse

it is a duel eliment light bulb probably, like a 1157 , replace bulbs or at least remove bulbs and check for burnt eliments... you can also check with a ohm meter...

Switch, wire harness problems, bulbs blown or wrong connectorposition fitted to bulb.
Connector bulb fitting you can check.
Wireharnes probleems:
Get 2nd person and a multimeter set for suitable 12 VDC range
Let him step on the break and you mesure between ground and +terminal of light bulb connector if there is 12 VDC. If all wiring gives Voltage when brakes kicked, harness ok. Then bulb/connector problem: correctly matched.
If no 12 VDC from wiring the left with harness or switch.
Small job, go to local dealer. Needs adjustment or broke.
