I have a 2007 Avanlanche and my alternator seems to be charging sometimes and not charging sometimes. I have taken it off and had it check and it checks out fine. My battery checks out fine as well. I was told that the alternator is controlled by the on board computer. I also have a bad problem with my battery being dead about once a month. I have changed batteries with no sucsess. I have herd of manyother people having this same problem. DOES ANYONE HAVE ANSWERS OF WHAT IS REALLY GOING ON???
I have a 2007 LTZ Avalanche
Thanks for any help.
