Replace heater blower motor

When i turn on the ac or heater past the lowest setting it makes a ruffling/whirring noise that gets louder as I move the settings up. It is still blowing but making the noise. Can you tell me what is causing this and how to access it to change it please?

    finding noise sources on complex cars, takes lots of patience, skill and danger (drive line) look for the exact source, buy a stethosope for $5 at harbor freight and listen at the HVAC path, across the dash, (from the under side) and put pressure on the parts, with your and to see if it change the sound of the noise or stops it. Noise diagnosis is a black art. vast tricks to do before , rippiing dash to 100 pieces.

Working in there is no easy task,
why not put pressure on all the HVAC parts in cab, one by one
as it makes noise, to see if the sound changes.
its the blower bad
or there is debris stuck in it.
or there is a loose part near by that vibrates in sympathy to the fan vib's , some times one can put a wedge in the parts casings and stop noise.

the HVAC is like 8 hour, in +out. horrid job. and lots of things can get busted doing it. collateral damage.

login to

and read the FSM , chapter HVAC.

SOURCE: blower motor noise

the blower motor is like round cage and the only way to get to it is to take appart the dash. not the insterment cluster but the top and through the glove box is probably the only access. i doubt you will find a schematic just take lots of pictures while taking appart of what each screw looks like as it comes out. most the heater vents are in your way taking them out is not only screws but plastic barbs. just take every thing appart that is plastic and keep track of where it goes the cage you want is dead center of the dash. you dont need to take it out just get access to it. also what ever got there probably fell from one of the vents that blows onto the windshield so the top of dash removal may be easier if all you need is access to pull out some trash.

SOURCE: How do I replace a Heater Blower motor in a 2003 Pontiac Vibe?

Remove the Glove box. You will then have access to the Blower unit. There are 3 screws that are holding the blow unit in place. You will need a Phillips screw driver and a 1/4 socket. Once you have located the unit remove the 3 screws and the unit will fall straight down. Unplug the wire harness and then reinsert the new Blower Motor. If you purchase an original GM part this makes life much easier, you just screw the 3 screws back into the holes and then plug the wire harness back in and reinstall the glove box. If you use an aftermaket part you will need to do some wire splicing to make it work but it is a 10 to 20 minute job depending on which part you decide to replace the Blower with.

AC Heater

It sound like the blower wheel of the blower motor is rubbing the inside of the housing (the smoke). Sounds like the blower wheel rubbing may have burned the inner plastic housing or has come off of the motor shaft inside. Take the blower motor and wheel back out and inspect everything closely I think you will find the problem.

1999 isuzu rodeo AC/Heater blower making noise

Sounds like EXACTLY what you described (I've had that happen before). There is a leaf (or similar plastic/natural object) in your fan blower. This is located under the dashboard, typically under (or most easily accessed from) the passenger floorboard. If lucky and like mine, it was a few bolts (3 or 4) to take the cover off (with the blower attached), and all kinds of dirt, and a big leaf, fell out. They get in when the outer air vents are open. Good luck!

When i turn my heater on (and also the ac) it makes a loud humming noise. as i turn it higher the noise gets louder. I have a 2001 chevy trailblazer.

It is possible that a stray leaf or piece of debris is stuck in the blower fan blades. This is more likely if the noise began suddenly. You will have to access the blower and remove it to inspect the blades. If their isn't an obvious debris problem, the blower fan bearing may be wearing out and getting noisy; although this noise would slowly get worse and worse every day.

2004 focus 80,000 miles/6 weeks ago, using ac with blower on high, blower gradually shut off and car produced bad smell. Drove home with ac off, blower off, had car checked and nothing found. Now it's...

The 'whirring' sound from the blower motor could be a dry bearing or damaged armature (part of blower motor that the brushes ride on), or just wore brushes. The smell could be the motor winding wires burning due to blower motor bogging down and overheating. You can replace blower motor with new or salvaged one.
