Thank you for your input on my situation. I can agree with you wholeheartedly "throwing parts at it" is not the answer. In my 31 years in the automobile repair business I have never been an advocate of that and in all reality it is actually ,in most cases, cheaper to let the Dealer take a look and diagnois the problem.
I do know that in a lot of cases , the concern that the customer brings to you, has occured before on "another" repair situation and this reference can be used to help repair the problem you are up against.
Basically my original question was, had anyone ever ran into this before? Sometimes it can be said that, for example the Blue wire under the battery in the left harness may have been a reoccuring problem, or a plug becomes corroded over time , or a short here or a open there,etc...
That is actually what I was looking for. Just took a shot that someone had run into this before and there was a "simple fix". Otherwise Ill move to plan B. Thanks again for the input.
