Like the blower motor going bad ?
Does it make the noise in any position, or just heat ?

    I guess it could be air or coolant flowing thru the heater core. You might want to make sure the cooling system is full. I would have to hear it to make any suggestions.

My 2001 xterra started making a weird sound between 20 and 35 mph. It sounds like there is a leak in some pressure system.

Common Car Noises and Their Likely Causes Noise More Details Likely Cause Fixing It Clicking noise while turning Starts faint, gradually becomes more noticeable until very loud Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age Replace either the whole axle assembly (recommended) or the outer CV joint Water pump noises Difficult to diagnose because of water pump's location Noise usually caused by damage to the bearings in failed water pump Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs Squeak or squeal from an engine belt Loud, high-pitched squeak or squeal Belts either need adjustment or replacing If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced Exhaust heat shield noises Rattle that you hear when car is idling Damaged heat shield Replace heat shield

My car is hard to turn, it makes an awful noise and is smoking, it smells like burnt rubber, if i continue to drive it what will happen

Hi Debbie,
Not sure with out looking at it, But from what you posted if hard to turn
sounds like your power steering punp aint working , ant if smoking and smells like burnt rubber sounds like pumps locked up, (pully not turning) and if so continuing to drive it could leave you on side of road if it runs a cerpintine belt , that kind of belt runs every thing and if breaks water pump stops flowing water motor will over heat, you should realy have someone look at that for you.

Is the Check Engine Light (CEL) on? If so, you need to take it in to a mechanic and get it checked for any diagnostic codes. Also, you can go to Autozone or other auto parts stores (call ahead) and they will check the codes.

It sounds like an exhaust leak - it could be a manifold gasket - where the exhaust pipes connect to the engine, or possibly another spot on the exhaust has a hole.

Hello I have a 1999 Chevrolet Silverado 1500 2WD (2x4). While I am driving i have a loud thumping (flat tire sound) coming from the right rear. You can hear it as well on the left just not as loud. when...

Sounds like it might be a damaged rear end. Chock the wheels or put rear differential on jack stands and put vehicle in neutral then by hand turn the drive line back and forth and see if there is any loud noise when u do. There should not be a lot of play. if on jack stand you can also turn one of the rear wheels and see if there is any load noises or excessive play

Yuck, this doesn't sound good at all. Stop using this truck until you find out where this noise is coming from.
Inspect the drive-shaft, look for faulty U-joints (you may need to drop the drive-shaft to see if one is binding), look at the gear-oil inside the drive-axle (is it full, does it have metal in it?), check for loose lug-nuts on all four wheels, check for cracks in the rims, and inspect rear E-brakes, They may be defective. Good luck, let me know how its going.

If you turn on any/all heating/cooling control and it makes a loud noise, it is probably your blower fan; they are normally located under the dash (some vehicles are easier than others).

If it's just your heat though, not a/c as well, then someone else will have to chime in...

Loud squealing noise

The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.

Engine revs realy loud

You have a faulty thermostatically controlled fan clutch. Same thing happened to mine. As soon as you start the car, the fan is always turning, and the speed increases as the RPM is increased.
