HiCustomer Thank you for asking your question on Just Answer. The other Experts and I are working on your answer. By the way, it would help us to know:
What is system voltage?Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.
I am so sorry , I was away for a day and your post was no on my question waitng list so I thought someone else helped you. I think your problem is going to turn out to be a bad ground-there are a couple places to check-I'll get the info together and post it shortly.
DId you replace the dash with a new unit or a used one? And the BCM? Also do your door dingers etc and dome lights etc work? One more thing I wanted to clear up-did the volts guage do the same thing with both dahsboards and BCM's? Im sorry this has taken so long-if you can answer these few more questions for me then I'll try to respond right away. These answers will tell me if the problem is in the harness or what. The symptoms you describe are very typical of bad solders on the instrument panel, so you can see my dilemma in finding out what changed if anything with the parts you repalced. Thanks for your patience.
