- 2000 Buick park ave
So I have a 2000 buick park ave with every option on it to make it an ultra with out the leather seats and super charger. I think I have a electrical prob, but don't know. My cruise works but the light does not come on, my temp gage says at cold, but thermostat has been changes. On the gauge cluster, tire pressure oil pressure temp sensor and oil life read ????. When it all reads ???? The Ac does not work. Ot is intermitten, sometimes it all works with the valley key, sometimes not, sometimes works with my original key, most of the time not. Any ideas?
