    instrument cluster repair - bad stepper motors that control the gauges. All the info for the gauges come from the PCM/ECM - engine computer over class 2 serial data network .

    Or maybe class 2 data bus problem - hook up a scan tool an check for DTC'S - diagnostic trouble codes , u codes lost communication with PCM / ECM If you don't know about this stuff your best bet might be to have a qualified repair shop check it.

You said it was raining? It pays to have a look at the fuse box near the battery and check the fuses and connections for any trace of oxidation. I will suggest to have a chat to your local electrician.
