Bmw - X5 :: Heater Blower Motor Making Shrill Noise
Nov 29, 2011
I have a 2005 BMW X5 and the heater motor makes a shrill noise only when I am turning right.

View 1 RepliesMy prius that I got about 1 1/2 years ago (2013 model) was making some noise. After conducting a few experiments I came to the conclusion it was the heat that was causing it. I removed the glovebox and lower plastic panel as well to see if it was actually the blower that was making the noise. And it was the blower.
So now it's like 20 degrees outside and I haven't used the heat because I didn't want to blow something so gotta get this fixed ASAP.
Like I mentioned glovebox and lower panel are open I've removed 2 of the 3 screws necessary to remove the blower. So the problem lies with the 3rd screw. There is a plastic socket with wires that is preventing me from reaching the 3rd screw so I have to remove that socket. So I have a couple pictures and how I can remove this so I can access the blower motor.
Also isn't it strange that the car isn't even 3 years old and the blower is giving me problems?
My A/C has been making a loud noise for a couple months now ,only when I put the A/C on the highest setting. I was LONG overdue for a cabin air filter change so I bought a new one and while I was down there I looked inside the blower motor and here's what I saw... It is now blowing fine and not making a noise . Sprayed some Ozium New Car spray on the new cabin air filter and my car is smelling great now !
View 4 RepliesI have a 1993 E350 Econoline-based RV. The blower motor intermittently makes a horrible whirring/buzzing sound, usually if on position 3 or 4 (high). Doesn't stop until I turn the HVAC to Off. The blower motor vibrates quite a bit while making this noise (verified with my hand). The problem occurs even if the engine isn't running. This started a few years ago, and has simply gotten worse.
Since it runs OK at the lower speeds (until the problems start with the higher speeds), I think that means I can rule out something simple like debris? Also, when the engine is under load (climbing hills, etc.), the blower fan cuts out. Could that be a resistor problem, or something else?
How hard is it to change the A/C/Heater blower motor. I know about the switch problems but this is the blower motor. I'll probably clean it out and spray something in it before I replace it but I just wondered how hard it is to get to. On another note, this 4 wheel drive Santa Fe rocks in the snow! I can't believe what good traction it has!
View 3 RepliesI got a new resistor since my last one was in a puddle of water and installed that today and still have no heater blower motor. I checked all the fuses and have power. I sent power to the blower itself and it spins good. So somewhere between the fuse and the blower it isn't working. I need to take the controls out and test for power there. Didn't have time to do that today. What wires to check or where to start trouble shooting?
View 7 RepliesWent to have an oil change....service rep came in with my cabin air filter and said it needed to be replaced, I told him "later" as they charge too much for a simple filter.
Two days later I had the need to run my blower on high and it vibrated rather loudly.. I tried different positions on the vent switch but nothing worked.. then it came to mind the Jiffy lube incident. I went in and pulled the cabin air filter out and saw nothing wrong there. Upon further inspection I found a piece of an acorn in the blower wheel.
Moral of this story...if you changes cabin air filter, be sure to check for any debris that may fall off the old filter into the blower wheel when it is removed.
Recently bought a 2003 E350. The front heater/ac blower motor isn't working. I found the control switch melted and bought a new switch. Before installing it, I need to do some diagnostics. I checked the blower with a couple of jumpers ant it turns and blows. I think that leaves the blower motor resistor. Where it is on a 2003 E350? I also need to check the relay. I have a power distribution box at the front left under the hood. Is the relay there? The box is not labeled like my GM products. Which is the blower motor relay? Finally, which fuse controls the blower motor? I read it might be a 40 amp fuse. If so, that might narrow it down.
View 6 Replies99 Explorer Blower motor quit working. Disconnected and hot wired to a battery and blower motor worked. So I know it is in the switch and/or wiring. I need this truck everyday so going into the shop is out. Live in Northern Mn and the temp was -15 degrees. So as a temp fix what does everybody think of running a wire from the battery to a switch inside and then to the blower motor and then to a ground. Would have a inline fuse. If this will work what gauge wire and what amp fuse would you use. Its getting cold without heat.
View 4 RepliesI am not great with electrical but can manage. Here's the deal, Ihave a 1997 ford ranger 2wd 2.3L 5spd with a/c 233,000 miles i just replaced the heater blower motor resistor as the old one was rusted bad as was the pig tail going to it bad that one of the terminals broke off and was rusted in the harness so i replaced the plug as well problem is i still have no fan if i jump it it works but have no power at the plug for resistor or motor and no power at the switch inside the truck I do have power to one terminal where the relay plugs in, where to look next?
View 14 Replieswith a new heater core, new blower motor, and new resistor and no heat, what would be the problem? gonna check the thermostat tomorrow.
View 2 RepliesI am new to the world of the Cadillac. I bought a nice 1994 Deville for $500 at auction. I replaced the water pump and put two new tires on the front. It is my daily driver I use for work, I put about 96 miles a day on it. The gas mileage is actually really good due to 90% of my drive is on the highway.
The only issue I am currently having is that the Heater/AC blower motor keeps running until I pull the plug under the hood. I started looking up solutions only to find that there really seems to be very little in the way of getting good information.
I have one side saying it's the blower motor itself
another saying it's the BMC
another saying it's the heater/ac programer
and still another saying there is no cure just pull the fuse
When I checked here I found one person with the same problem back in 2011, but there was no resolution.
2001 f350 blower motor for (A/C - Heater) works sometimes and sometimes does not.
View 5 RepliesI have a 2000 Ford Windstar Van with 155,000 miles on it. A problem has developed with the electrical system/components. The van will start and run fine. With the engine running, there is no instrumentation, power windows do not work, wind shield wipers do not work, radio does not work, heater blower motor does not work. After the engine has been shut off, the radio will work, windows will work, door locks until such time as you open the door, then all quits. With the key in accessory, the windows work, door locks work, radio works, etc. The neutral module was replaced (the old one, none of the contacts appeared to be burnt). Ford dealer spent an hour trouble shooting - checked body modules (2) - found nothing.
View 4 RepliesMy wife heard a humming noise on a 200 mile trip to Long Island last week. It was loud enough that she was concerned about it and took it into a Toyota dealership to have it checked out. Of course, the noise went away, and they assured her that the car was perfect!
When she came home, I drove the car and the noise came back. Radio was off and the frequency of the noise changed with the AC/heater blower speed. Turn blower (fan) off, and the noise completely disappears. Before I got home, noise disappeared again with the fan on. I believe it is a bad bearing in the blower motor.
I'm getting this weird chirping noise from what sounds like the A/C and Heat fan. When I turn it down it is noticeable and sounds like something needs oiled. Kind of like pieces of plastic hitting each other over and over again. When I turn the air up there's no noise but probably because the air rushing out is so loud. I'm thinking I may need to take something out and oil it up. Too cold here to do my own thorough investigation.
View 4 RepliesI have 2011 SE (2.4L) that has a VERY noisy squeak that increases with the climate control's blower speed. The noise stops completely if the fan speed is set to OFF. It has been rectified twice by the dealer, who said they just vacuumed it out or something, that there was leaves/trash somewhere causing this. I don't even park near trees or anything! Anyway, my car is now out of warranty, how can i do this myself?
View 5 RepliesPurchased 2011 Prius 2 with 108500 miles on 4/29/2015. Didn't fully check all climate control settings and fan speeds. Two days later, car had vibration and rumbling sound which was increasingly severe on three highest climate control fan speeds in all modes (e.g. AC, heat, auto, manual, etc.). Sounded like a quiet lawnmower on highest fan speed. Was quiet on three lowest fan speeds. Glove box and passenger side dash vibrated in sync with noise.
Cabin air filter had been replaced by a large Toyota Dealer as part of pre-sale prep. I suspected filter was not installed properly. Removed glove box and filter, which had been properly installed. Vibration/noise were same when fan was operated without filter or glove box installed.
Felt around inside of fan housing. There was debris, including seven pieces of acorn shell (see image below). The concave sections of the shells were firmly wedged in the fins of the squirrel cage (no pun intended!) impeller. Cleaned out all nuts and debris, reassembled, fan operated quietly without vibration at all fan speeds.
The shells essentially unbalanced the impeller and induced vibration at high fan speeds, just like an unbalanced wheel would induce shimmy or vibration at freeway speeds. What is baffling is how the debris and acorn shells this large got past the filter. Filter fit on the right side is pretty good since a plastic flange goes between the pleats. The left side appears to have a looser fit with some gaps.
My Prizm is making a noise that seems to be related to the blower but sounds like it is coming from behind the control panel/radio. Even changes volume and stops with bumps. I am going to check the blower motor motor, but sound doesn't appear to be coming from the dash area where I believe the blower motor is. What else it may be?
View 4 RepliesThe car is a '99 Volvo V70 XC AWD. The blower for the heater wasn't working this morning. When I left work it was blowing a little but not as high as it should on full.
View 7 RepliesSo for a few months now, my car has been making a subtle clicking noise whenever I have the ac or heat on, kind of similar to the noise spokes on a bike would make when children put a card in them. The noise increases/decreases in speed as I adjust the ac/heater speed.
Recently though, it's gotten to a point where sometimes, the blower motor would completely stop working. I can still feel heat and cold coming through the vents when I turn the AC on, but the it doesn't always blow air. I've noticed that sometimes when I hit a bump in the road, it starts working again. It works at all settings and all temperatures perfectly (when it's working that is).
How should I proceed? I don't know much about cars, but from what I've seen on the internet, it doesn't seem too difficult to replace the blower motor. I just want to be sure that the blower motor is indeed the cause, because I don't want to install a new one to be disappointed when I turn it on and still have the same issue. And winter is just around the corner so I would love to get this taken care of.
