My 2004Kia Spectra will not blow out heat or air


Sounds like the fan is not working. Does it blow air on any setting? If only on high, your resistor is faulty. If not, the motor, switch or fuse/relay may be at fault. Check these out first!!

Heater / air conditioner fan control doesn't engage fan. Previously, it only worked in high speed.


I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

Heater and air conditioner blower switch.


Check the resistor first. It may be bad. Should be under pass. side of the dash close to blower motor mounted in bottom of evap case. Remove it and try known good one first before going at the switch. If it works on high then the switch may be okay. Good luck.

Check the wire connections at the blower motor and fan resistor, they are located under dash on passenger side. They sometimes have corrosion that burns the plastic connector. The resistor is responsible for all fan speeds below high. Hope this helps, let me know.

Heater switch


So your saying that regardless of what setting you put it in your blower motor doesn't blow anything? correct?
If this is the case the problem is with the blower motor.
Have to check switch, relay , resistors and motor.
My bet is on the switch.

Heater fan only works on "high speed"


All cars are designed with a blower fan motor that pushes air through the ventilation system. This air is processed by a series of vents to direct the air to various positions. Example: heater, air conditioner and defrost modes. Most blower motors are power by a basic electrical circuit that utilizes a multi resistor or a solid-state resistor to control different fan speed modes (low, medium low, medium and high). If the resistor malfunctions it may lose one or more of the lower fan speed settings.

1995 GMC A/C fan only works on high???


Two possible problems. First the Freon level might be too low to allow the low pressure protection switch from letting electricity get to your compressor's clutch. This is just a 'most likely' reason, there can be others.

But then you definitely have a problem with the heater resistor pack that is mounted in the heater's air stream somwhere behind the glove box. This device allows for low, and medium fan speeds but needs to be cooled or else it will melt and open up electrically. When that happens you 'loose' fan speeds except for high which is 12 volts direct to the heater motor.

This year GM pickups needed the HEPA air filter but did not have one so that all manner of hay trash, leaves and you name it would plug up the air conditioner evaporator inside the cab which in turn stopped enough air flow to the heater resistor pack which causes it to fail and you wind up with no DOT required defroster AND carbon monoxide preventing air flow into the cabin. There is law and how they avoided a class action suit is beyond me but you are looking at about a hundred dollars to replace the resistor pack and heater switch too.

You might have minimum success blowing the trash out of the evaporator backwards after you take it all apart, as a passenger when you kick the 'heater', that is right where you need to go to clean out the evaporator. It's only 1/2 inch thick and on the bottom of the pile.

If you have good air flow on high then you can disregard the blowing out of the evaporator and just concentrate on getting to the resistor pack - we just changed it with the switch panel to get it all done with in one shot. There is an outside chance that fixing the resistor pack/switch will return your compressor's voltage as well, there is no telling how that switch has it's failsafes integrated.
