I have a 99 toyota avalon the dash lights went out and when the bright light are on the radio lights and shifter lights go out but when you turn the brights off lights the lights on radio and shifter come back on is it a short or a fuse issue

Read your question, can you make sense of it??
Neither can I. It sounds like a car brights you every time you drive your car.

unplug the radio harness and try the dash lights. if they work, then there is a wire that is connected incorrectly. sometimes the harness has an illumination wire that can cause problems like this.

Did you check the fuses?
