I have had this issue for a week now when suddenly the airbag light came on and followed by A/C shut down and gauges moving up and down working intermittently. I took the car to the dealer and did resetting to the ECM/PCM program, but they suggested to change the speedometer cluster due to circuit shortage. I took the car to another expert electrician specialized in speedometer cluster and he said that it is altered and reduced to a lower km previously( I am the second owner), but it could be the body control module(BCM) needs to checked or changed. I already placed online purchase to get a used speedometer cluster before asking the electrician and costs alot.
What do you think of the cause?
Where can I find the BCM?
How can I make sure that it will work after replacing the speedometer cluster or BCM?
