Check inside the car undre the dash , check the heater core.
The heater blower motor itself is located under the hood on the passenger side of the car.
Maybe it is out of antifreeze? If older car, maybe you need the radiator and heater flushed.
Means that your heater core is leaking coolant. Has to be replaced.
Sounds to me like the heater core is leaking coolant.
This is actually common for most cars. The reason is that the heater pulls heat away from the engine into the car itself.
This probably means that your heater core has sprung a leak ; you will probably find the passenger side damp form the leak itself - check with your mechanic .
you first have to have a block heater (frost plug heater) instaled on your car... they dont come that way from the factory
If it is smoke the heater fan motor has failedORElectronics in the heater have failed ORif it smells like anti freeze rather than smoke the heater core has failed.
you must go to you local dealer and buy a heater box assmbly the door is not sold by itself.
You would have a leak, from either the pipes to the heater matrix (radiator), or the matrix itself.
Do you mean where on a car is a block heater install or who do you take the car to to install?
