it needs a new blower motor resistor ....
It usually shouldn't, but if it does, it should only stay like that for a few moments.
A car heater taps off engine heat. If you aren't driving, then the engine is cold and there's no heat for the car heater to use.
Because the car needs all the power it can get to start so you heater and maybe radio cut out for a few seconds.
Why does your 2001 Nissan Pathfinder heater fan stay on high even after I try to shut it off?"
The battery runs a fan that pushes air through the residual engine heat in the heater radiator into the car.
well for one is your keyed turned all the way off. But i would say you probably have a short in you wiring somewhere. But try turning off the heater while the car is running then shut your car off.
car cuts off
check your thermostat or your heater core may be getting ready to go out
They stay on cause they runnin off the battery. there should be a car headlights switch somewhere by your spedometer stuff...

MaybeYou may have it on "auto" not off check all switches off You may have a faulty selector switch. Also some vehicles always blow heat even with the heater off.
