    "Short in my heater" is a vague diagnosis and probably not accurate. Find a Mazda specialist or an auto electrical shop and get a second opinion. I think it's possible that the control unit is failing, but nobody could really say unless he diagnosed the system and came up with a malfunction.
    No idea what it'd cost but shops usually estimate in an agreed number of labor hours to find and diagnose your problem. then you know what it'll cost to fix it.

    Sounds more like a loose plug or cracked cable, which ive solved on other manufacturers too. a short to heater would keep it burnt fully and forever, never seen a e-motor or heater "running sometimes" when theres a short in it.
