The alternator alone cannot fully charge a battery, it can only get it to 60-80%. If your battery dies and you get it jumped, it's never gonna hold more than 60% until you plug it up to a $20 trickle charger and let it sit overnight. Your blower motor is probably weak as fuck and you don't even know it because you never gave the battery a full charge after the first time it died.
