Hello i have a 97 Oldsmobile Cutlass Surpreme, its a four door and my brake lights do not work except for the top one. We have checked and replaced bulbs, and the switch under the pedal. Also the blinkers work.
Do the turn signals work?
OK. You may have a problem in the turn signal switch. The brake lights circuit goes through the t-signal switch in the steering column.
There is a quick little test you can do to confirm this.
First, are you sure you adjusted the brake switch you replaced properly? Because if the switch was bad, then you replaced it but did not get it adjusted, it would act the same- no lights.
pretty sure yes
OK. Then to test the turn signal switch, turn the key on, have someone watch the lights in the rear, and someone else move the turn signal lever very slowly, not so fast as to activate them, just move the handle up and down. Many times if the switch is bad, you will see the brakes lights flicker.
If that does not help, then the other thing is to rapidly move the turn signal handle all the up then all the way down, harshly and several times. This will sometimes free up a bad switch.
ok awesome i got on here for my bf thanks a lot.
