Having problems with your 1997 Chevrolet Lumina ?
Brakes lights don't work, only 3rd brake light does.
\015 Yes my cruise control works, but the brake lights don't. only the 3rd brake light works.\015
If your third brake light is working, then we know it is not the brake switch. Get a test light and check to see if you have power at the light socket. If power is present possible bad ground. If no power, check connections inside of the trunk. Also choose a spot just behind the back seat to be sure that power is on the brake light wire, this will check for possible break along wire.
