Check to see if blower is working by running 12v to it. If that works check if your heat/ac controls are working by looking at the area where the flaps are and turning the knobs/buttons. You should hear the flaps move or see the pins of the flaps turn. See if your heater core is working. Should be hot as coolant from engine passes through it.

SOURCE: Honda Civic heater / blower noise.

you need to remove your glove box assy.(beleave only 2 screws and pivot clips) make sure its not anything from glove box that has slipped behind. once box is out uf way you can access easier the blower motor assy. it actually attaches into blower box from bottom side. when looking at you will find three screw/bolts fastening motor to casing. remove those and then slowly lower motor and fan cage(attached to motor shaft) out from housing. sometimes it takes a little convincing to come out but not real tough. once out you most likely find the object causing noise in fan cage or resting up on lip area of housing unit. once found install in reverse order. let me know if this helps or if we need to dig a little deeper into! good luck!

SOURCE: 99 Nissan Altima blower fan works only on highest setting (#4)

Resistor switch. The rotary switch on the dash is very, very uncommon. It is also not the blower, because it works.

Testimonial: "Thanks for the help, it was the resister assembly like you suggested."

1996 chrysler cirrus heater fans not blowing hot air to vents or defrost. Not sure of actuator or thermostat. Since i dont know where they are. 2.5L V6 - 4 cylinder.

I will assume that your engine is full of coolent, and does not overheat. Now if your car takes like forever to heat up, It will be that your thermostat is stuck open, but after a while, you would have heat in your car. If your engine coolent hoses get hot, but your heater hoses do not, remove the heater hoses where they connect to the engine. This is the first place dirt, grime, and corrossion build up, stopping the flow of hot coolent from going through your heater core. (heater hoses stopped up at engine/waterpump connection.) Your heater core may also be stopped up if there is alot of corrossion present.

The thermostat is located directly under where your upper radiator hose connects to the engine.

Hi guys I am new on this, I will start all over, I got this big problem for me, I got this 2002 huyndai elantra gt, 1 week ago I was driving and the heat stopped working, no radiator leak, everything...

Ok, here is my take on your problem. As you may already know, it takes a car a few min. to actually warm up to operating temp. When the coolent reaches operating temp. the thermostat opens to circulate the coolent in the radiator. Now, as your drive, the air pushing against your car will actually blow some air through your heating system ducts and into the passenger compartment. Is it possible that your blower fan isn't working? Because while you are stopped, there would be no air forcing its way through your ducts, thus no heat. As your drive, your car gets up to operating temp, heats up, and the air pressure as your drive will blow some heat out into the passenger compartment? On a side note, if your thermostat is stuck in the open position, it would take it forever to warm up since it is circulating ALL the coolent even tho it isn't at operating temp. A thermostat stuck open will take 30 min or more before you actually feel any warmth, if at all in the winter.. your thermostat opens and closes constantly as the engine is running to keep it at its normal temp, usually around 160-180 degrees. If you live where it gets really cold, a thermostat stuck open likely will never get warm. If your blower motor works, and your engine don't overheat, im 98% sure its your thermostat.

Blower only runs on high

please see my post at http://www.fixya.com/cars/r6234839-doesn_t_heater_or_air_conditioner_blow

remove the glovebox to access the motor and resistor. Unplug the cable from the resistor, unscrew it, remove and inspect for heat damage. Please let me know if the resistor looks good or if you have any questions.

My heater has quit working and i know my thermostat and heater core are working what else could cause my heater to stop working and i also know its not my blower motor

heatercore could have a restriced flow. feel both heat hoses and see if they are hot and both the same tempalso heater may work better at lower speeds. if that is the case, you might have too much fresh air mixing with heated air. under the dash and thru the glovebox will give you access to the mixind doors and maybe you can find which one makes heater work better. sometimes it as simple as a vacum leak to mix door motors

I have a 1994 honda accord lx..heater fan was makin funny noises for a while..then stopped working..started working and stopped again..Is it hard to replace..could it be a fuse..I;m a girl..could I do it...

The heater fan is on the right side floor board under the dash. It is a little tough to do but not extremely hard. If the blower was making noise, it could be something in the heater housing. If it is starting and stopping it is probably the blower motor. When replacing the blower motor you may have to remove the fan from the motor depending on where you buy a new one. The fans (usually made of plastic) break very easy. If you attempt this, be very careful in removing the fan.

Under the dash on the right side you will have to lay on the floor and look up. There may be a lower dash panel to remove. The motor is just below the glovebox. Removed the wire, remove the bolts/screws attaching the blower to the housing. Remove the blower.

The heater in my 1998 Lincoln Mark VIII LSC doesn't get warm. The fan works and the AC works, just no heat. How do I fix it?

You have a problem with your blend door actuator. Every year, twice a year, my husband manually moves the blend door actuator and puts a tie wrap on it so it will stay in either the heat or cool position. You can reach this through the glovebox, which you will need to remove. I had this fixed at the dealer once long, long ago - very expensive because the plastic piece that needs replacing means they must remove the seats and the whole dash area including the steering wheel to properly replace what is broken. If you want to see how that is done go here: http://www.mechanixtrix.com/Article/Article.aspx?ArticleID=145 Much easier going through the glovebox.

Motor heats up

If the fan is working and water is circulating, it could be losing pressure. Replace the radiator cap or on some vehicles the coolant refill cap. I had this same issue with a Grand AM.

No heating or fan working

You may need to check the fuses first from there you may need a new fan swith or relay or maybe a new fan and also a new heater core.
