Where is the Voltage Regulator located in my 2005 Buick Terraza? I think this needs to be replaced to fix my charging system failure. I've been looking online and i cant find it
My car has an automatic transmission.
The voltage regulator on your car is integral to the alternator. If you have diagnosed your charging or electrical failure as due just to the voltage regulator, you should request GM part number 15926088.
