1997 olds cutless brake lights will not work. bulbs, fuse and switch are good

foot pedel switch probly

If the high mount light works, and you know the bulbs are good, the problem is probably in the turn signal switch.

there is a switch mounted above your break pedel .install that break stop switch and you should be good.

The turn signal switch and the hazard switch are likly places to look. To checjk the fuses is'nt to take them out and look at them but to test to see if power will go though them, I use a test light ( a tool that looks like an ice pick with a wire coming out of the handle and the handle is clear with a light bulb inside). with the clip connected to a good ground as you touch the back sides of the fuses the light will light if it only lights on one side, the fuse is blown ( does'nt matter what it looks like ) a bad fuse can look good. the turn signal switch is involved as is the Hazard switch. If you pusth the hazard switch and the lights light good then you know that the lights and the sockets are good. You also know that the wires are good . With the key on the turn signals should work front and back ( thier different cicruits) If only working in the front the turn signal switch is bad provided the hazards worked all the way around. Does the high mount stop light work? It works off of it's own circuit on the brake light switch and if no lights work your back to the fuses only after you checked to see if the high mount bulbs are good. Your car is plenty old enough to have them be burnt out. If the high mount doesn't work with the bulbs known to be good and then you check with the test light to see if the power isd getting to the brake light switch. One wire is hot with the key off and another comes hot with the key on ( the cruze control switch in the brake light).

There are TSB's for this issue. I chased this issue for months on mine. Go find the TSB's, there's troubleshooting pointing out the faulty part. It could be, the brake light switch, the hazzard light switch itself, the multi-function switch. I had replaced all of these and still had the problem. Wiring that goes from the brake switch to up near the fender was shorting against the fender. I replaced the pigtail, problem fixed. Best bet to help you, is find the TSB's for this problem.

As for the brake lights push brake pedal down while pushing on and wiggling the hazard switch.If the brake lights come on then replace the multi-function switch.

If the two rear brake light are working on each side, then fuse and relay are good, check the bulb.

check the brake pedal switch by connecting a test light to it and ground.

When the pedal depresses you might hear a click or see the button depress.

The test light should light or not light changing as you press and release the pedal.

Another way to do this is to change the brake pedal switch and see if it works.

I hope this helps.

take out the bulb holder then have some one step on the brakes then pull on the black neutral wire like 1/8 of an inch and the buld will light up.

ASE Mechanic here:
Check all the fuses. pull out one by one. if one is bad it needs replacing anyway, right! Good if that doesn't work, check power at the brake switch mounted on the brake pedel, you can up plug and jump across the terminals and make brake lights work. Keep me posted!!!!!!!!!
