1996 Plymouth Voyager No Brake lites when I apply the brake

I've checked the bulb in the rear, also the third brake lite has 3 12 volt 921 bulbs I replaced. I checked the fuse box under the dash, and I checked the fuses and relays in the engine compartment. I also checked the brake switch mechanical operation, I didnt check for current at the brake lite switch on the pedal I didnt want to short anything out and deploy the air bags. I'm stumped.
