Voltage regulator is in the altinator. Its the insert wiring piece you plugin the alt its a 2" black plastic chip that regulates your out put charge

Have the charging system thoroughly checked, if I remember these vehicles the alternator is computer controlled, so you really don't have a regulator that is a repairable unit.

In the alternator. Replace it.. I personally have one with 270,000 miles on it. Works fine as well as a/c and starter
