Heater fan don't work,don't know which fuse operates heater fan

there is a fuse that says htr on it thats the fuse.

Could you be more specific on what was fixed? and i would start by checking your fuses, do you hear any sounds when turning all the knobs? sometimes you can hear the heater flaps moving around when adjusting temp, the fuse for the fan probably is blown.

Both "blower" fuses are fed by the ignition switch. If there is no power to those fuses than the switch is the likely problem.

sounds like it could be a bad flasher and for the fan there is a fan relay i would suggest checkin that out

David I dont have th schematics for your fuseblock layout for your vehicle but when I am having problems with a component in my vehicle I use a pair of pliers or a fuse puller and pull all of the fuses one at a time and check them for being blown. If I find a blown fuse I replace the one blown with the same size. If you are having problems with the fan motor I would suggest that you find where the wires hook up to the fan and check them for 12volts using a volt meter. If you have the voltage chances are that the motor in the fan is no good. Hope this helps

The fuse for the blower motor/heater-a/c fan is located in the fuse panel under the hood of the vehicle in the engine compartment. Below is a diagram of the fuse layout. The fuse you are wanting to check is the fuse in the number 103 position and is one of the "maxi" fusesrs. If you would like the owners manual for your vehicle you can email me at [email protected] with your make, model and year and I will be happy to email you a copy. No worries no cost for it. I hope this helps and good luck.

The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

My 2002 I35 has the blower fuse under the hood in the fuse box in the engine compartment. The fuse box cover has the "key" or description of which fuse is which. If the blower fuse is bad and you replace it, only to have the fuse burn again then I would check the blower resistors that are located behind the glove box. Very common for one of these resistors to go bad causing only low speed operation of fan. Burns the fuse when you try to operate the fan on the higher speeds. Good Luck

yes under hood or dash if fuse is good check your elec. plug on heater fan housing may be burned up replace plug if still bad fan motor is no good
