SOURCE: Alero loud humming/roaring sound coming from front end.

That's indicative of a wheel bearing, which is why you were told to change that out. However, it's also possible that the carrier bearings in the differential (where the drive axles attach) have gone bad. That happened to me on my 300ZX several years ago, and I had to replace the diff bearings. I would have them checked out somewhere other than a dealer (you'll probably get a better price from an independent shop).

As a sidenote, to be sure it wasn't a wheel bearing, if you hear it quiet down in a turn one way but get louder in a turn the opposite way, it's likely the wheel bearing. If you turn left at speed and it gets louder, then it's the right bearing (since you're loading up that side of the car). If it gets quieter in a right turn, it's the right side (you're unloading that side of the car and not putting as much weight on it, so it doesn't drag as badly). See if you get that symptom just to be sure that the wrong side front wheel bearing wasn't changed.

SOURCE: 2004 alero making loud screaching noise by tire

It's the belts. Quick fix is spray some kind of silicone lubricant on them, like tire shine. You should really replace the belt or belts that are making noise, also check the belts tension. Too loose and they'll make noise

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.

AC cools then blows hot air, tempature needle goes up & down


Sounds like the thermostat is trying to stick,and is causing the engine to over heat,therefore condenser is not cooling the freon down enough to cool.Have the thermostat changed and the cooling system bled out,this is most likely the cause.

Could be the flap that directs the air flow. Are you getting air flow to all vents? The flap is inside the venting and controlled by a vacuum operated actuator.
