My brake lights do not work everything else does replace flasher unit and brake light switch checked all fuses and wiring all seem good on a 97 eclipse

Check for power and ground to the lamps. Most likely you have lost ground, since you replaced everything else.

The flasher unit is located under the dash, near the steering column. This could also be caused by a faulty ground wire. Check the wiring for broken, bare, or loose wires or connections.

Most likely this is a brake light switch issue. Replace switch.

If your emergency flashers don't work, all flasher bulbs are fine, but flashing too fast, then check and replace Hazard light switch.

turn on the emergency flashers(e-flashers)if they work check the bulbs at the same time.if this is good then check the fuses.you may have a problem with the turn signal flasher needing replacing.this is a different flasher than that of the e-flasher,looks the same but a different flasher.usually located on or around the fuse panel under the dash.the brake light problem could be a misadjusted switch or a bad switch.the switch is at the base of the brake pedal and has two wires to it.one wire will have power all the time and the other wire will only have power on it when the brake pedal is pushed.if not then the switch will need replacing.check for broken wires at the switch as these sometimes break causing a problem.

OK if the fuses are good , use a test light and check to be sure you have power at the fuse terminals. you'll check from ground to the terminal on top of the fuse. you should have 12vdc. then , check for power at your brake light switch on both terminals while the brake pedal is pressed, it is located located on the brake pedal assembly. also , check your hazard flasher switch to be sure it is not on. if it was on, check your flashers, both the turn signal and hazard flasher. If everything checks out , your problem is probably in your turn signal switch assembly located in your steering column.

there is a flasher for both 4 way & regular turn signals ( check to make sure the bulbs are good
the backs are easy >>> Just step on the brake, If the lights light up the bulbs are good you my have to remove the bulbs one at a time in the front check your ground wires to the lights if everything is good replace the flasher unit if that fails replace the turn signal switch

Lets keep it simple if the wiring harness is in good condition lets not look at that... first check your fuse if the fuse is good... check for power... if you have power coming and going from the fuse then check your brake switch ( located under the dash) attached to brake pedal. Please make sure your light bulbs are both good also. If your brake light switch is good and you have tried everything else it is either going to be in your 4 way switch or wiring harness

Check your fuses of course,you probably did.Listen your not going to believe this,the wire at the brake light switch can be bad.sometines the wire can break inside the vinyl cover just a milameter.use a test light for presence of voltage at the switch and check a few inches back to see it voltage is present. MAKE SURE YOU HAVE VOLTAGE AT THE SWITCH!

Sounds like a short in the steering colume, maybe the turn signal switch, or a wire that the insulation got wore thru in the colume. Unhook break light switch and try the turn signals and hazards again and see what happens, maybe you can isolate it that way. Also if you havent done it already chk.the sockets in tailight housing for corrosion and bear wires, or anything, even ground wires.

i would check it,seems u have an open circuit,switch not working,broken wire or corroded elect.connector.
