Hey I was wondering if anoyone have this problem with there cavalier/.Sunfire? I have a 98 Z24 and my rear brake lights as well as third brake light arn't working, my signal lights don't turn on at all, not even on in the dash, I also have the abs light on in the dash, my rear defrost doesn't work at all , and horn.

It happens all at the same time, so when the signal works, the brake lights,rear defrost,horn and abs light is gone, very weird I know. I already tried replacing the multi function switch and the Ignition switch and neither one fixed it, just wondering if anyone knows what all this is connected too to creat this problem that it affect all I listed above. thanks!
