There is a large amount of leaves or pine needles in the blower wheel. It most likely gets worse the higher the blower setting, the faster it spins...........
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.
there seems to be a short in the electrical system, i would start by checking the heater switch,
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".
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.
This may be a misfire caused by a low fuel pressure.
If this is about a car: the heater in a car is basically another radiator, but this one sitting inside the car. When you turn the heater on you draw heat from the engine and into the car. If you aren't running the car hard enough the temperature in the engine will drop.
The heater core is basically a small radiator located inside your car. If your "real" radiator isn't working quite as it should, then the heater can carry some of that load. Then if you turn the heater off the engine will run hot when it's only got the bad radiator left to cool it.
