I have a 2006 Chevy Trailblazer, I just replaced my bad alternator to find that the idle is still bad. My lights dim when my A/C is on and it feels like it is going to stall. I checked the plug to the Actuator Solenoid and did not find any oil. Now, when I turn my wheel all the way to the right/left, it almost stalls out and my inside volt meter drops quickly.
