SOURCE: Very loud Hum under driver side

I concur. The ABS pump gets an internal short and runs continuously even when you turn off the ignition key. Mine was replaced under warranty but I believe parts and labor are around $1100 US at a dealer. Note, the dealer is the only place you can buy it, no aftermarkets to my knowledge. You could go to a junk yard and pull one of a silverado there?

SOURCE: when i start my car i can hear a knocking noise

Itmay be a foreign object inside the blower motor, a bar blower motor or your engine is bad, have a technician scan it to be shure.

Look at your wind deflectors that are in the roll bars behind the seat.

SOURCE: Loud humming noise from under my Tahoe 2 WD

Is it closer to the back of the vehicle or the front?Possibly the fuel pump. Try opening the gas tank and stick your ear close to the intake of the tank while someone turns the key.

Low pitch humming noise


May well be. You might want to check your coolant. If you're low (but not yet overheating) your fan will come on more often.

Noises from axles can be really deceiving. The sound is transfered throuh the transaxle and can resonate through the entire vehicle. The turning to the left thing makes it sound like a problem in the right wheel/axle area. Wheel bearings and axles tend to make worse noise when they are on the OUTSIDE of the turn. More of the vehicle weight is shifted to the outside due to centrifugal force. Thus, if the noise is louder when turning left, this puts the right axle to the outside of the turn and the most likely to be the source of the noise. (and vise-versa) The fact that the noise calms down while cruising makes me believe that it is not a wheel bearing. Wheel bearings can make more noise in turns, however, they usually make a "roaring" or loud "humming" noise that gets louder with speed. An axle is more likely to change or get louder according to engine load more than rotational speed. (Way worse while accelerating or climbing a hill) I would be taking a hard look at the right axle.

Humming noise coming from engine


Engines do not produce humming noises.... more likely a worn bearing from a pulley.
Have your Alternator tested it may be under stess and not working properly thus giving a humming noise.
All the best.

The humming noise you hear is the fuel pump. It is probably your starter soleniod. If you hear an electric click under the dash near the steering column when you turn the key then the ignition switch is ok and your starter needs to be replaced. This happened to me last month.

Had this problem. You need to have the heater controls tested. Your engine management goes through the heater/climate controls. When the control starts to go bad you will experience many things from difficult starting to fan controls that only work on 1 or two settings and worst of all, constant battery drain. At it's worst our Trailblazer was draining battery in less than 2 hours from full charge. For a year we used a battery cut off from an RV under the fenderwell, lol...

Strange raddling noise from front passenger side


if the noise only happens when the vehicle is in motion...check the front suspension. place the jack under lower control arm ,then get a bar and lift up on the tire..ball joint issues are well known in blazers and cause this condition. if it does the rattle noise when its idling and to op temp--could be the cat converter causing the noise on pass side directly under passenger seat. when cold, smack the cat with rubber mallet and if any rattle is present, cat should be replaced so it dont cause further damage .hope that was helpful !!

I have a whistle or humming noise from the front of 05 Montana.


Put wide tape on different areas of the windshield edge as a test to see if the noise changes.Then you may know where the noise originates and can correct the noise.
Just by chance,it is a wind noise? and not a front wheel bearing going bad?which is common on these vehicles and can create a humming at different speeds.Next time when the hum shows up turn the steering wheel slightly left and right at road speed and if you can change the hum,it's 99% a wheel bearing.

Knocking under valve cover on cold starts


Is there any smoke when you first start it? what is happening is the valve seals are probably worn and letting the oil seep past them. when your engine is first started it has no oil or very little oil at the top of the engine, thus causing the knocking noise. could be more but this is a most likely answer. oh and is you haven't changed your oil every 3,000 miles you had beeter start doing it.... answer knocking sounds usually come from bottom of engine try a better quality and correct viscosity oil

Very loud Hum under driver side


There is an ABS fuse under the hood that you can take out, and the noise will quit. The noise is accually your ABS pump. They are kind of expensive.
