Where is the voltage regulator on a 1999 Chevrolet Blazer?
On a 1999 Chevrolet Blazer, the voltage regulator isn't a separate component like it used to be on older vehicles. The voltage regulation is integrated into the alternator itself. You won't find a separate voltage regulator to replace. If you're having charging issues, the problem likely lies within the alternator as a whole, and it'll need to be replaced or rebuilt.
