And the dash was dead at this point drove it home dead. Shut car off . And replaced battery in key fob. Car would start as soon as I pushed clutch in without hitting button. But would not shut off I took key inside away from car and it still would not shut off . After replacing the battery in fob the key light still comes on and will not start like it should if I play around it will start sometimes but still will not shut off. It threw a code for loss of communication to HVAC. Only code that is in it anyone have any ideas
Thank you

If everything is dry, I'd try removing a terminal from battery, press on brake pedal for a few seconds, and reconnect battery. This resets the ECM, auto-up window operation, and radio presets. It will take a few minutes of driving around for the ECM to re-learn the engine, the window reset procedure takes about 30 seconds. The difficult part will be re-entering the radio presets.

Edit: the ECM is somewhere in the passenger footwell - check it for moisture. Not sure where the BCM is located but would check it too.

Be safe.
