Help!!! 2002 brake lights screwed up

My rear window brake light works but the tail lights do not. have eliminated the bulbs and fuses, don't know where else to look. Please help. Is there a switch or relay that may need to be replaced and if so, where is it?

Would that not still be covered under warranty?

Like DRW- says, hopefully you are not over 36Kmi, in which case should be under warranty. Do you have a trailer hitch / trailer wiring? These can cause issues due to poor or corroded connections.

Vehicle has 37,000 miles. I called, but they wont cover it. Do not have a trailer hitch.

If the 3rd light works, then the brake light switch and fuse are good. Sounds like the LCM (Lighting Control Module).

My manuals are at work, I can pull up the diagrams later and see if there are any other likely posibilities.

Thanks, where would the LCM be found? Please advise
