Not the core making noise it is most likely the blower motor or the fan cage attached to the blower motor... most blowers are attached under the dash on pass. side or under the hood at the pass. side firewall area attached by approx. 5/6 #8 metric small bolts opr 1/4 inche or the like, it has a small black vent hose attached to it that also needs to simply be pulled off ...this will give you an idea where the blower is, the fan cage once you pull out the blower and disconnect the electrical plug and ground wire is mounted on the blower motors shaft with a #10 or a 3/8 inch or the like nut retaining it on the shaft.

SOURCE: heater blower makes noise on high speed

it is either a bad switch or window motor. finding a wiring diagram and shooting power to the correct wire will identify whether the switch or motor is faulty.

SOURCE: heater blower makes loud noise

You need to lubricate the 2 bearings on the motor. Takes about 30-50 min to take the area under the hood apart to get to it. It is in the housing underneath the Wiper assembly. Go to benzworld.org or peachparts.com for possibly pictures on how to do that.

Heater is blowing cold air and there is a noise coming from around the blower motor area?


Check your coolant reserve tank and fill it if needed.

If the coolant is fine try flushing the heater core, follow ChrisFix's instructions in the vid linked below.

As a side question:
Were there any loose wires that could have been caught near the fan when you replaced it? They'll make a buzz noise if they're touching the fan blades.

My heater works but makes an awful loud noise when i turn it on in my 1997 Geo Tracker. Any idea what would cause this? Since heat is coming out I assume the blower motor is working.


got A/c option?
noise can be caused by many things
from bad blower bearings, to something stuck there.
or just loose vent ratting. is just a blower. in a box and some vents and dampers. those too can get loose.
why not use a rubber hose to ear or better buy a $5 stethoscope at the autostore and find exact point it makes noise. with this tool.
also you can press on vent pipes with hands, so see if that cause the noise to stop. or get better, and you can watch the damper
lever,, to see, if they wiggle and rattle , ?

step 1: defeat air bags, (a great danger to all fidders there)

for 100% sure nobody can guess on the blind as bat forum.
get car serviced"?
could even be a dead mouse there, crawled down cowl vent
then in to heater boxes. (if a/c opted, he must stop at a/c core...)
or same for tree leave and tiny branches, working down that same top front cowl vent..
i had one that whole cowl was packed in dead tree parts.

I have a 2011 jeep and recently my heater has not been working. When it does it makes a rattling noise and it also does not heat the feet.


there are these things that must work first.
1: engine hot.
2: heater core hot.
3: blower runs full speed on high.
4:dampers working.

there are simple tests for each, do you want us to guess. or tell you
how to do tests.
first tests is
fan blows full speed, surely you know that sound and know flow
at all vents in all modes. did you try all modes> up, lower, both levels>
and do you get heat moving fast in, non recirc mode (fresh air )
do you, if yes, the core is working, check off #1 and 2
leaving blower.
if the blower makes noise, (using a $5 stethoscope) then it does
have problems. only you can tell us this fact we can not listen
to any car , here in net bunny land.

What could cause a grinding noise when turning on the blower?


It is the pressure release valve on the AC unit. The system is clogged so it's creating too much pressure and tripping the valve. Hoses and possibly more needs to be checked and replaced. Probably due to a sealant being used.

Heater core or thermostat


Nothing in or around the heater core could make a noise. The core is just a small radiator with coolant circulating through it. And if you feel both heater hoses, and both are hot on a warmed up engine, then coolant is circulating through the core and the heat should be working. There must be a door in the heater case that is not letting heat come out.
The noise may be from the blower motor and its plastic fan assembly. It should be pretty easy to take out the blower motor and check for any obstruction.

Churping fan noise inside car behind the middle heater/air vent and a smell of burning oil or anti-freeze coats me and my clothes while inside car Help Help.


Not familiar with Saab at all, but on every other car made, if you smell coolant inside the car and a fog covers the windows, the heater core needs to be replaced. Depending on the design of the heater box that contains your blower motor and heater core, leaking coolant may be destroying your blower motor, and causing the noises and metal smell.

My Tempeture Gage in my car goes up way too fast and warm air is not blowing into the vehicle. There is occasionally a clanking noise near the heater core underneath the center of the dash, I have no idea...


recheck fluid fill and reservoir, Make sure waterpump is circulating, Is the occasional clank when operating controls? Possible air flow control door sticking or binding. Also a possible heat air bubble popping in core. Also fan blower motor making contact with housing or blower cage

The heater a/c or defroster will not work in my car no air will blow through the vents


Is the fan turning (do you hear it)? If it's blowing, but not passing the blend door, then that would describe why it doesn't deliver air to the passenger compartment.

Poor Heater System Performance CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.
  1. Start the engine.
  2. Idle the engine until the thermostat opens (upper radiator hose will be hot) Is the engine at normal operating temperature (approx. 200° F)? If yes, go to the next step. If no, go to step 16.
  3. Set the mode selector to FLOOR mode.
  4. Set the heater control selector to the warmest temperature setting.
  5. Set the blower speed the lowest setting.
  6. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 14. If no, go to the next step.
  7. Set the mode selector to PANEL mode.
  8. Select the maximum blower speed.
  9. Select the warmest temperature setting.
  10. Place a thermometer into the center I/P PANEL air outlet and affix a second thermometer to the heater core outlet heater hose.
  11. Record the temperature at the center I/P PANEL air outlet and at the heater core outlet heater hose. Are the two temperature readings about equal? If yes, go to the next step. If no, go to step 13.
  12. Inspect and repair the cowl, cowl area, recirculation door, and the HVAC evaporator/heater core case for cold air leaks. Repair any problems found, go to step 17.
  13. Inspect the temperature door operation. Repair any problems found, go to step 17.
  14. Turn OFF the engine. Back-flush the heater core. Start the engine. Select the FLOOR mode and the lowest blower speed. Select the warmest temperature setting. Feel the temperature of the inlet and outlet heater hoses at the heater core. Is the inlet heater hose feel significantly hotter than the outlet heater hose? If yes, go to the next step. If no, go to step 17.
  15. Replace the heater core. When the repair is completed, go to step 17.
  16. Check for low engine temperature problems, Repair or replace as needed, go to step 17.
  17. Operate the system in order to verify the repair. If the system operates properly, the repair is complete. If the heater still does not work properly, repeat the entire procedure.
Insufficient Defrosting CAUTION
Check all fluid levels and adjust as needed, before operating vehicle for extended periods at idle.
  1. Start the engine, select the DEFROST mode, and select the maximum blower speed. Does sufficient air flow from the defroster outlets? If yes, go to the next step. If there is insufficient airflow, go to step 9.
  2. Measure the engine operating temperature. Does the engine reach normal operating temperature (approx. 200° F)? If yes, go to the next step. If the engine does not reach normal operating temperature, go to step 7.
  3. Select the minimum blower speed. Select the warmest temperature setting. Carefully feel the inlet and outlet heater hoses at the heater core. Is the inlet heater hose significantly hotter than the outlet heater hose? If yes, go to step 10. If the hose temperature feels approx. the same, go to the next step.
  4. Test the operation of the A/C compressor clutch. Does the A/C compressor clutch engage? If yes, go to step 6. If the compressor clutch does not engage, go to step 5.
  5. Inspect A/C compressor clutch and controls. Repair or replace as needed, go to step 13.
  6. Determine if the A/C system is operating within specifications. If yes, go to step 8. If no, go to step 11.
  7. Check the low engine temperature problem. Repair any problems found, go to step 13.
  8. Inspect for correct operation of the recirculation door. If the door is operating correctly, go to step 13. If the door is not operating properly, go to step 12.
  9. Check air delivery system. Repair any problems found, go to step 13.
  10. Check the heater core for blockage. Repair or replace as needed, go to step 13.
  11. Check A/C performance. Repair or replace as needed, go to step 13.
  12. Repair the recirculation door concern. When the repair is complete, go to step 13.
  13. Operate the system in order to verify the repair. If the system is operating properly, the procedure is complete. If the system is still not providing proper defrosting, repeat the entire test.
Noise from Blower Motor
  1. Inspect the air inlet grille for debris. If the grille has debris, go to step 7. If the grille is clear, go to the next step.
  2. From inside the vehicle, close all vehicle doors and windows, turn ON the ignition, with the engine OFF, and cycle the blower motor through all speeds in order to determine where and when the noise occurs. If noise is heard during the blower operation, go to step 3. If there is no noise, go to step 10.
  3. Inspect for excessive vibration at each blower motor speed by feeling the blower case. If there is vibration, go to step 5. If no vibration is present, go to the next step.
  4. Listen to the blower motor at each blower speed. Is the blower motor making a squeaking or chirping noise? If yes, go to step 8. If no noise exists, go to step 10.
  5. Remove the blower motor, and inspect the blower motor and impeller for deposits of foreign material. If there is debris, go to step 7. If there is no debris, go to the next step.
  6. Inspect the blower motor impeller for cracked blades, loose impeller retainer, or improper impeller alignment. If any of these conditions exist, go to step 8. If none of these exist, go to step 9.
  7. Remove the foreign material, go to step 10.
  8. Repair or replace blower motor or impeller as needed, go to step 10.
  9. Install the blower motor, go to step 10.
  10. Operate the system in order to verify the repair. If the condition has been corrected, the repair is complete. If noise still exists, repeat the entire procedure.

Blower motor makig noise like its hitting


You must remove the motor to inspect for bent squirl cage (fan) for damage .your heating issue is seperate from the noise.you could have a bad thermostat check your temp gauge if its at least half way up to 200 degrees thermostat is ok then you will have to check heater core hoses for flow in and out to make sure they are hot. if all check out look at blend air doors make sure they operate.

Honda heater makes loud noise


ok well its possible there may be something stuck in the blower motor under the passenger side dash. ..or the blower motor itself could be on its way out, sometimes leaves or sticks from trees and even stove inside the glove box can find their way into the windshield cowling and into your blower motor..u can remove it to check by unplugging its white connector and remove the 8mm bolts that secure it into the heater core box..its very easy to remove..the 8mm bolts / screws should also have a phillips head on them...
