Thank you all for your input and the manual...it is what tipped me off on the 5 button control switch. I think this car has been in a wreck and only put parts in to make the insurance policy on what it would cover...explains the wrecking yard numbers on bezel and some other things. I will finish ...

Does anyone know why the DIC in my 03 Bonneville SLE doesn't display all the information it suppose to.
