    Maybe start by checking your fuses?

    I would start by asking the heater for any trouble codes. This is even easier than checking fuses.

    Hold down the AUTO and FRESH/RECIRC buttons while powering the car on. Look for any two-digit codes shown on the usual heat/AC display. If you post those codes here, we may recognize them.
