The odometer, fuel gauge, temperature and A/C not working, how to fix this?

Hi,

Did they all fail at the same time? If they did, it could be related to the body control module (BCM).

Let me know if they failed together. If so, here is what I recommend. Have the can-bus scanned. CAN stands for controller area network. Basically, all the different 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 link that explains how it's done:

Let me know if you can have this done and as much info you can provide as far as how the problems came to be.

Take care,

Joe
