Hi,

Wow, it sounds like everything has stopped working. I doubt that many fuses failed at one time or if one wire caused it. Let's try a battery cable reset.

I need you to read through the attachments below and perform the procedure indicated.

If this doesn't help, we should scan the can-bus system for diagnostic trouble codes. CAN stands for controller area network. Basically, all the computers/modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. Here is a quick video showing it being done.

Let me know if that is something you can have done or if it has already been done. Also, let me know if you have any questions, and if this started all at one time.


Take care,

Joe
