Both rear signal lights are out, so are brake lights. Driving lights work, so are high beam lights and all front turn signal lights. What should I check? I have done some research, but I could not locate the fuse or the relay flasher for my 2004 Malibu Maxx. Appreciate any help here.

Your taillights work, if I understand your post. Turn on the head lights and have someone observe the tail lights. Step on the brakes and if the tail lights go out, then you have a broken ground wire.

See if the emergency flashers work in the rear and if the middle brake light works ok also. The brake lights and turn signals run through the emergency flasher unit. Cycling the flashers switch a few times may help fix the trouble.

How do I find and fix the broken ground wire? Neither the emergency flashers work in the rear, nor the middle brake light works, although the emergency flashers work in the front.

When I press down the brake pedal, braking lights are off. Braking lights are always off. I.e. regardless engine on/off, headlights on/off, braking lights …

Since you say that the brake lights are out, does the cruise control work? The cruise control is deactivated when you press the brake pedal. If your cruise control isn’t working, you may want to check the brake light switch.

I will try the cruise control after work. What if the cruise control is working? It has been a detective work lately on finding the cause of the darkness behind my car. Appreciated your help.

I haven’t dealt with a brake light switch for 50 years when I replaced the switch on my 1947 Pontiac. This switch was on the master cylinder. However, I think more modern cars the switch is under the dashboard, clips on, is activated by the brake pedal lever. I think you can unplug a connector fr…
