Question about 2004 Jeep Grand Cherokee
When the headlights are on and the brake is pressed, taillights go out. When the brake is released the tail lights are fine. When the headlights are off, everything is fine.
Try checking one of 2 things, Check the fuses. I had a 94 cavalier do the same thing after i put a 30amp fuse in to a 25amp slot for the courtsy fuse. Also check the bulbs in the tail of the vehical to make sure they are the right ones. If this dose not do it get a test light & wire diagrham, you may have a bad short to ground some where in the brake light wires.
