I am sorry that you have not been helped yet. I just came online and saw your question

First, have you checked the fuses? If not, do you need a layout of the fuses to know which ones to check

I also need to know if you have a scan tool that can read body control module for fault codes and whether you have a digital volt/ohm meter(dvom)

Customer: replied 1 year ago.
All fuses are ok, No scan tool.
The car died as I was driving it.
I put a new battery, since the other was 4 years old, checked the charging system it shows a little over 11 volts, so I think I need an alternator now.
Could that be the cause of all gauges and speedometer/ instrument panel not working?
Expert:  Eric replied 1 year ago.


Yes, low voltage will create all those conditions as they are not getting sufficient voltage for proper operation. Replace your alternator and this will resolve the issues.

Directions are a bit different between 2wd and awd versions, so I have uploaded each for you
