    Hey again y'all. I chased a drain in the following thread but it has returned. At this point, I have no power at driver or passenger's door except that I can move the driver's mirror as expected.

    Alternator and battery questions 2014 Tahoe LT

    Intermittent chirp I’ve always had that I think comes from the alternator, it’s not to loud. I just changed idler pulley, so I don’t think it is that. My battery voltage is always eratic, it’s always different when I start the truck, but the voltage will stay between 13.4 and 15.2… Valvoline...

    Should I go dual battery?

    I’ve got a 06 Tahoe z71 and I want to add a better radio and better speakers and put in a wall outlet like a 110v socket in. I figured I wouldn’t need dual battery for the radio and speakers, but should I get it if I put in the outlet?

    First cold morning of the year.... Go to start, it lights up, but when I turn to start, nothing, not even a starter click. Put it on the charger, then go to start after a few minutes, and now it says service anti theft system and it won't start. On a whim I go and get the other key from the...
