I would disconnect the fan connector and use contact cleaner to clean the connection. Usually corrosion. Also fan might be going bad (Common Problem).

I have a 2007 kia spectra. My heater or ac will not blow air, I can feel heat, but it will not blow air


Check the fan in the vent system. It could be broken or could have something stuck inside stopping the fan from turning.

Fan for heat and ac wont blow air. Makes A loud clicking sound


mcdevito75 here, The heater/Ac fan motor is a sealed unit, locate the fan motor, as you look at the engine from the front of the car the fan motor will be on your left side comming out of the firewall, It"s a round cylinder like and is black, from inside the car put the fan on, tap the fan motor itself with a screwdriver, small wrench, etc. see if it"ll start, if not have your local shop replace this fan motor.

My heater stopped blowing this morning.


Your heater blower fan unit is in need of replacement.
It's a difficult job so take it to a service center.

Heater/AC fan does not blow on two lowest speeds.


Your fan uses resistors to reduce the speed of the fan. Hi speed doesnt use the resistors and that is why it runs on hi. Standing in front of the car, all of your heater housing is on the left side of the firewall You will see a connection with about 4 wires That look like they go nowhere. Take the couple screws out and pull it out. You will be able to see the burnt one.Jump out the burnt on and that will give you another speed or two.

Heater or ac fan does not blow, ac still cold, fuse where is it


Yes, but more likely the fan speed switch is defective or the blower is defective
