there seems to be a short in the electrical system, i would start by checking the heater switch,
stalling, but not often?
Weak battery or starter.
It depends on your car, but should be very obvious.
Alternator is not making enough power.
To go out about 5min. early and turn the car on and heater so that the car can be warm when you leave.
No heat when you turn it on in the car.
your car gets warm............ or hot........
the heater of your car does not only work when the car is in motion. it only works when the engine is started. you don't have a heater in your car like you do your home. the heat that you feel when you turn on your heater in your car is produced by the engine. and there for if your car is not on then you will not receive any heat. some cars take longer than others to "heat up".
to stall your car
no, stalling only makes your car stop for a brief moment when shifting geers to fast or not using the clutch correctly
There is only one thing you can do if your Heater in your car is not working. You will have to take it to the dealership and have them look at it.
Sounds to me like the heater core is leaking coolant.
