Heater blower went out?

About 1 yr ago, the medium-high setting on my heater went out. No big deal, cause the other settings still worked. Now, when I turn on the heater, I only get very little heat on the highest settings, yet I hear the blower/sensor (behind the glove box) click as I switch control from Low-Med-High. Is this the blower that isnt working?

    Didnt notice any smell. The blower still comes on, but the high setting now blows equivalent to low setting. While the low setting doesnt seem to blow at all. I can hear what I think is the relay, behind the glove box, clicking as I move between settings. Is there anyway to check the condition of these parts(blower,relay,etc.), without replacing them?

Either the blower went bad or the heater relay went bad. This does not sound like a heater core problem unless you where smelling a SWEET smell when it was running.

    Yes, in order to do this you will need to remove the dash around your system, and with the car key in the on mode you can take a multimeter on DC and check for power, This could just be the relay switch that is bad in that case you will get a reading on all setting but one

Heater motor barely works on high. wont work on low or med. settings


blower is not running full speed? on high?
the blower has this resistor block on many cars,
that fail, easy. (burn up) but not ever on high. (bypassed then)
a big clue that. no?
is the blower slow or just dampers closed and cant feel it.
surly you know the sound of your blower on high, sound !
air flow is a whole other more complex matter.
also is battery rested voltage at 12.6v? if not you have discharged battery making fan weak ( power = volts times current. so....)

What causes heater blower to barely work on high? wont work at all on low


A couple of possibilities; air path blocked by debris (mouse nest, etc.), the sleeve-type phosphor-bronze fan bearings are clogged with wear particles, less likely but still possible is a failing blower switch, failing ground for the fan motor or an oxidized fuse or fuse holder.

A multimeter would be handy to isolate the source of the problem.

With your headlights on and shining on a vertical flat surface, try noticing if they dim very briefly when you quickly turn the blower on.
If not, then the fan isn't getting full current, if they do, then this would indicate a bearing problem with the fan.
Good luck-

05 GMC sierra heater blower stopped working. It used to work on setting 1-4 but lost 4 a couple weeks ago and now none of them work. Is this a bad blower , resistor or both?


The resistor is most likely bad but should still work on the highest setting.Would check pigtails to the resistor and to the blower motor for burnt or discolored wiring.You can try tapping the blower motor and wiggling the wiring harness too see if it will work on the highest setting. It is possible that the blower motor is bad as well typically when you lose the speed selection it is the resistor but you should always have high speed.

I have a 1992 chevy lumina that only the high on the heater control works. i have replaced the control panel the blower module checked the blower motor still only works on high.


either the switch or there is a resistor pack in the heater duct that gets burned out and only 1 side works if it is not the high medium low switch check resistor pack mounted in the heater duct.

Humming noise coming from my 1994 cadillac deville especially during the hotter months


Late model Cadillac Deville's and Seville's may experience a humming noise in the passenger compartment when the heater is on high and the blower is set on a medium to high speed.

GM has determined that the most likely cause of the humming noise is from the positioning of the blower motor within the HVAC housing, causing a restriction of the incoming airflow. (GM TSB 03-01-37-001)

The recommended repair for this symptom is to reposition the blower motor.

1. Remove the right side sound insulator.
2. Loosen the three blower motor retainer bolts. (Do not remove bolts)
3. Shift motor as far as allowed toward the vent tube.
4. Re-tighten the retainer bolts.
5. Re-install right side sound insulator.

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.

I have high speed blower but no medium or low


It's likely a relay. I've often seen where the lower settings are ran through one relay and the higher setting ran through another because of the difference in amperage. I'd start there, the relays are often pretty cheap and a lot easier to replace than tearing the dash apart to change the switch.

Hi, sounds like your blower motor resistor needs to be replaced. If not the resistor, check the blower motor.

A/c fan only works on the highest setting...not the lower ones


A/C fans only really have (2) speeds. (0)Off... and (4)On. Settings 1,2,and 3 are governed by a series of two resistors which in combinations (one, the other...then both) can limit the speed of the fan. When the circuit with these resistors goes bad, the middle speeds of your fan will cease to work. Since the highest setting is unresisted it will never stop working... unless your fan fails.
The solution is economical as these are simple inexpensive parts. For simplicity, the panel with the resistors is typically located in the dash, right behind the speed selector knob. It may be an integral component with the knob assembly depending on your manufacturer. Replace the assembly, or simply the resistors if you are lucky. On the bright note, it doesn't sound like you need to mess with your blower moter... its fine.

Cheers, unclouded.
