    sounds like you have a short in the wiring or blower motor. check all the connections first to your heater control for tight clean fit. and the blower motor at the plug in, for loose connection. brushes may be bad in the blower motor and is shorting against the case and won't run when hit right gets motor started until next bump. Check these and go from there.
