I have a 1978 coupdiville Cadillac my blower quit working and there is a relay above your fuse box and if it goes bad your heater wont turn on. I had to replace it with a after market heavy duty relay away from where it is originally plugged in. Also my ground wire connection was dirty and wouldn't turn on until I cleaned the connection so try that and see if it works or you might need to replace the motor.
either the battery or the starter motor is bad but, i dont know how an engine will try to start if it wont turn over maybe you could give more details of what it is doing
probably your ignition coil going bad.
Common causes, blower motor resistor, blower motor, wiring or controls

The blower on a 2002 Nissan Pathfinder won't turn off if the switch is stuck in the on position or the relay is defective. Removing the blower fuse will cause the fan to turn off.
You don't say the reason for the blower motor replacement. Did it not blow ? If that be the case, and you do have a new blower, check for 12 volts to blower. Could also Abe a malfunctioning blower module. Now if its blowing COLD air, well , replacing the blower moter wont make it blow warm. There could be numerous causes of that problem

If the cooling fans will not turn on, check the pump to make sure the belt is turning the pump. Also check the blower resistor. This large fuse is usually located on the fuse box for the battery on most vehicles. On older vehicles it might be located on the blower motor itself.
Check the blower motor to make sure its working propable
AnswerIt is an Electric Blower, And it senses that the vehicle is still very warm, so it keeps running to cool the engine -Mr. Mechanic-Could also be the blower motor resistor if it wont turn off at all
Could be, a bad blower motor, a blown fuse, a bad resistor, a bad switch, damaged wiring,
Blower motor bad. Blower resistor bad. Switch bad. Fuse blown.
