The engine coolant flows the engine, and becomes warm. The warm fluid then goes through hoses into the heater core. The blower motor pushes air through the core, letting the now warm core heat the air.
Get the air out of your heater core.
The heater motor speed resister is burned out.

how is it my heater control on my ford fiesta flight 1998 only works on no. 4
the reason for water coming out from under the dash is that a hose could have broke or you have a problem with your heater. your heater works off of the water in the radaitor and since it gets hot from the motor well it serculates threw the heater and that's who your heater works
You need to start out by checking the a/c-heater controller and the a/c-heater doors behind the dash for proper operation..............
This AC/Heater unit works best for a room size of 10 x 15.
Replace heater motor resistor.
Probably the Heater Fan Thermostat. It may have a different name.
