I have somthing wrong with my heater fan it does not work

How hot does the engine get in degrees F? Does the radiator fan work? You may need to check coolant flow through the radiator and heater code? With a warmed up engine, are the heater hoses hot? If the blower motor works ok, just not warm, check temp actuator, probably under the dash.
Any applicable trouble codes?

Cud b bad connect or its failn. Need to get toit for the test. Its a big project..so while ther..test heatr core and ac evaporator

check the connection on your blower motor resistor ,you mjght need a resistor

Your not going to work on it yourself anyway

You go to a repair shop don't you

Go to You Tube Video they may have somthing
you can watch

Replace the blower motor resistor assembly. To locate the electrical connector for the blower motor resister, it is usually attached to a heating or air conditioning Duct, or the blower motor case. You can also trace the Purple Wire from the blower motor back to the resister. Also make sure that the blower fan is not jamed up with somthing in side and will spin freely,or binding same thing, this will also cause the fuse to blow right away. And does the motor actually spin a bit before it blows the fuse or does it blow the fuse at the same time the switch is turned on? Good Luck and have a good XMASS.

I assume that you are talking about the heater fan?

Your heater FAN has at least 3 settings, and for our purposes we will assume low,med and high

Low and medium run through a resistor High is wired direct
Either your resistor is bad or your fan is
I know it seems wrong that the fan could be shot but it could be pulling so many amps that it won't work in any other mode than high
I just had this happen on one of my trucks
Start with the fan

My 1992 gmc pickup keeps blowing heater fuses I have replaced blower motor can you help me jody.

Hi,
My first line of action would be to check the fuse for the fan motor. Your owners manual should direct you to the fuse panel location. Hopefully, that's all that's wrong.
Hope this helps... Good luck!

Do you mean that the blower isn't running or that it doesn't get cold? Check the fuse box and see if the fuse is blown for the fan. Check any relays as well. Does the fan work with the heater on? If it is not getting cold it could be low on refrigerant and the system needs charged. Anyways, it is somthing to consider. Hope it helps and good luck.

dont take me up wrong but leave it to a mechanic incase anything goes wrong like gear box falls on you or anything mechanicly goes wrong u'll have no come back on it cause if a garage does somthing wrong or breaks somthing he has to replace it free of charge
