Hello - either the relay is stuck in the "On" position from burned contacts or the heater switch is similarly stuck in the "on" position (internal contacts at least). I would recommend an electrical inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
