HI i am Greg I will try and help

As you know these type of issues can be tough. Lets start with my first guess. open the driver side door. remove the small panel on the side of the dash. inside there is two largeish style connectors. disconnect and inspect them for water intrusion or corrosion.

does the car have onstar?

Customer: replied 1 year ago.
no
Expert:  Greg Jensen replied 1 year ago.

Sounds like something is shutting or interfering with your data comm but that can take a lot of time and testing to find.

I'm not sure of any addtl easy checks. I'll opt out and you can see if someone else has any different exp with this and knows where to look.
