First time I've posted on here. I need help fixing my SE before I get pulled over. The Turn signals and speedometer and tach quit working 6 months ago. At first they wouldn't work once started sometimes then start working 30mins into my drive to work. Now they don't work period and have been out for months. The speedometer tach0meter turnsignals odometer trip and tire pressure wont clear. I have seen others on here with this issue a year ago but nobody ever posted the final fix. that's if they found one.

2000 Bonneville SE

Problem solved. It was Inj3 relay in fuse box under rear seat. After buying new dash cluster pcm and body control module. Just a simple relay. Lol. So that's how to fix this issue folks.
