My third brake light works but the lower pair do not. The lower pair are also blinkers which work. I replaced the bulbs & the brake pedal switch to no avail. Please give me an idea of what to try next and/or a wiring diagram.

Wild guess: Bad ground that can't handle the brake lights but can handle directionals. Hard to find and I would test adding ground and see, T

The lower brake lights are wired through the turn signal switch and with you saying that the high mount brake light and the turn signals work I suspect the turn signal switch is the problem.
That’s where they split the connection between the signals and brake lights so that with the brakes and signals both turned on; one will flash and the other will be on steady.
Go to the last connection in the wiring harness before or at the turn signal switch. You should find a white wire there; it should have power to it with the brake switch activated. If you do and the connection between the harness and switch is good replace the turn signal switch.
If not trace the white wire back until you find out where you’ve lost power.
There is a splice in this white wire before the turn signal switch where the wire splits and goes in three directions. One to the turn signal, another to the high mount brake light and the third to the ABS module. This splice is suppose to be in the “dash harness behind the left side of dash”
Keep it fun.

You have probably already solved the problem, but I have a 2000 sunfire and the same thing just happened to my car. It was the hazard light switch, the hazard lights turn on by sliding it right and off by sliding it left. If I push it forward just a little bit when they are off my brake lights work. It you didn't fix it yet, give this a try.

Excellent! Have been working on this for about a week. Same problem, did what you said and pushed forward on the hazard light switch, pushed the brakes, and BINGO! You just saved me at least a hundred bucks. Now all I have to do is replace the module.!! : )
