In order to access the fan you need to remove the wiper assembly, its underneath Check all of your fuses first! Relays too! Usually these cars have electrical problems first! Before buying any parts check all the fuses and relays it will save u time and $$$!! If not electrical, its located under the winshield wiper assembly behind the firewall. Its not hard to get to.
If you have lost a sufficient amount of coolant this will stop the heater working because there will be no hot water in the heater rad.
If the seat warmer on a 2004 Saturn Vue is not working it could be a problem with the heater element. This element can be found under the seat and will be easier to access from the rear of the seat.
There could be multiple reasons why a heater would stop working in a truck. There could be low coolant or a bad fuse to make a heater stop working in a truck. The best way to find out the reason is to take it to a certified auto mechanic.
If the air conditioner in a Mitsubishi Legnum is not working, there could be a blown fuse. There could also be a loose cable, or a problem with the heater motor.
You have to be more specific. What is not working?
Check the thermostat, also there could be a heater core issue...
A blocked heater hose could cause a leak. A stopped up heater core could as well. Or the connector in the Windstar could be cracked.
That or the thermostat.
Could be your fuse, blower, heater core,loose ac belt, thermastatt or low coolant.
Could be low on freon,
Your car could be low on antifreeze or your heater core could be clogged. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
If you are absolutely, positively sure that your coolant level is not low......then your heater core could be plugged. Or the control that turns the coolant flow on/off to the heater isn't working. Make sure the control is working, the flush the radiator. Should cure the problem.
could be thermostat or heater fan if you can hear all the speeds on the blower motor working then it could be your thermostat but your heater core might be plugged as well
That's really going to come down to the reason it's jammed. Could be as simple as just working the mechanism, it could be a matter of cleaning and lubricating the mechanism, or it could need replacement parts.
sounds to me like your blowe moter is shorted out. u can use a test light to check for power at the motor,if you can also pull fuse out of fuse box to check fues BUT the blower motor will notstop heater working if no heat ,it is your heater core
Blower motor not working: could be the electric motor, or A fuse, or A short. Blower motor working: could be low engine coolant, or A stoped up heater core, or loss of vacumme to the inside of the car from the engine, or A bad water pump, or A bad thermostat.
Thermostat stuck open or a clogged heater core. Service and flush the cooling system and replace the thermostat.
Low coolant level, or a plugged heater core.
One reason that the heater will not work in an Audi A4 is that the fuse is blown. Another issue could be a short circuit in the wiring.
Assuming the blower is working, the reason for no heat could be, low on coolant due to leak in coolant system, thermostat stuck open, heater core plugged or temperature blend control NG.
Could have a clogged line feeding the heater core. Disconnect return hoses from the heater core and verify coolant is flowing through the core.
heater fan blower motor is burn up not working need to replace it could also be a heater relay typically located on the fuse panel that needs replacing could also be the switch on the switch panel
Check your fuses!
Assuming you have checked the water and its topped up, could be thermostat blocked.
Check for a blown fuse.
