When I turn on my right turn signal the brake lights and the right turn signal flash. Also when the right turn signal is on and you press the brakes the brake lights and the right trun signal go solid. I have done a lot of research on the web and found mulitiple areas to check. Have you seen this or herad of this? I need to know where to start checking

Replace the flasher. I have seen it quite a few times. It looks like a large relay on the back of the left instrument panel fuse block. Make sure you get the same part number as there are a few different options. You have to remove the knee bolster panel for access
