My car has a communication issue or so I assume. Starts right up and drives, no hesitations. It comes up "power steering" on the dash but my power steering is working fine. My cluster panel says I have no speedometer, no temperature gauge, fuel range gauge, econ and no average speed.
I replaced my BCM, TCM, battery (due to battery light flashing on and off when this all started), also replaced alternator and belt as recommended by mechanic) I've cleaned up every ground I could get to. I'm at a loss.
Any advice will be appreciated!

Hi,

Are there any diagnostic trouble codes? Also, have you tried scanning the can-bus? CAN stands for controller area network. Basically, all the modules are tied together via a few wires. In this case, if there is an issue within the cluster, there should be a code related that ties the can-bus into the equation. It's a theory at this point. Not being there and knowing exactly what you have already done, this is where I would start.

Here is a link that shows how to perform this type of scan:

Let me know.

Take care,
