Well, lets try this, if you have a trailer connector tapped into the tail lights check that for a grounded wire. If a wire has grounded or come free from the splices they won't work.
Thanks a ton for the educated response. I've never had a hitch harness installed, but actually just crawled up and under with a flashlight in the garage to see if I could find any reminants from a previous owner with no luck. I've seen mention of the steering column turn signal switch possibly being teh culprit, but it's not addiing up how all turn signals would still work and how that may affect the liftgate light as well.
Actually that is possible. I prefer to check the most common causes first. You checked the fuses in the fuse box in the interior, make sure you check the fuses and relays in the Power Distribution box under the hood. The blinker switch could be the problem but in isolating this type of problem I usually start by looking for the trailer connector, then looking at any alarm that is installed, after checking both fuse panels. As a last resort the flasher unit itself which is actually a relay under the dash, usually close to the fuse panel. since at this point you are having to test by replacement to find the problem the flasher relay is the least costly of the options. If someone has installed a radio or amplifier that was spliced into the power circuits they may have accidentally tapped the brake light power line which is normally hot all the time. If the radio is factory and no amplifier was installed that can be eliminated as a possible cause. IT really sounds like your problem is going to end up being in the area of the dash because it effects all 3 lights and you have already replaced the brake switch. An alarm being installed after the vehicle was purchased and wired in incorrectly could cause this but that can be easily eliminated as a cause by removing the power wire to the alarm in most cases. To eliminate the possibility of a broken wire between the brake switch and the lights use a direct wire from the battery or other positive source and apply power directly to the wire going to the brake lights. If the light come on then the problem is not a broken grounded wire. If they do not come on then you have a broken wire or grounded wire somewhere between the brake lights and the power source. This happens a lot when people go 4 wheeling or if someone had an accident and repaired the vehicle but the repair techs did not detect the pinched wire.
Both tails lights out. I have found out what the problem is! It's the hazard light switch on top of the steering wheel housing. Slightly push the swith sideways toward the drivers door with key on and then puch the brake pedal to check if the brake lights work. I got a piece of rubber and a penny, then wedged it on the right side of the hazard switch and push it down to lodge it the housing for a quick fix. So that means that the turn signal switch control has to be replaced because the hazard switch is made into it. [email protected]

Not sure if I understand your statement about "they work when hazards are on...". Do you mean the brake lights work when hazards or turn signals are on?
The fuses you checked, are they #12 in the underhood panel and #34 in the rear panel?
