Customer Question

I have a 2007 trailblazer 4.2 was over charging, replaced alternator then was working fine. then the a/c compressor went. now once the engine at highway driving of about 45 min to 1 hr the voltage drops to 12 volts. had it checked at auto zone said it was voltage regulator. replaced alternator again and voltage still drops to 12 volts. when you turn off ignition then start back up it starts at 14 volts then goes back to about 12 volts after 45 min of highway driving again
