Hello Everyone. I have a 2005 TBlazer that has developed a whine in the alternator area. It is definately an rpm driven noise. I thought it was the alternator due to the recent headlamp dimming with alt gauge showing a quick drop in charge rate and then recovery. My dealer seems to think it is my idler. I don't see the connection between the idler and short discharge though. I have a $100 deductable on my warranty, but they say the idler fix is under the $100. R and R of the idler looks pretty straight forward to me, so I'm looking to handle that myself if it is truly the issue. I can change out the Alt, but they are $168.. I'll let the shop do that one. Any ideas what might be going on here? Any help is appreciated. Thanks.
