Sort out the charging system and battery first, put it on a charger overnight, then move on to the heating system.

It sounds like the blower is binding/dragging on something, improper installation. This will eventually burn up the expensive motor and/or the speed-control "porcupine".

The blower speed is electronically controlled based on need when in auto, in high it should run high (but still electronically controlled).
