Could be the bearing in the fan motor going bad.

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

1996 Oldsmobile LSS. Went to autozone and got code PO133. 'Fuel system running rich or lean- check other aacodes first.' and 'Oxygen sensor defective'; The guy said it probably isn't the oxygen sensor; as...

code P0133 is : o2 sensor circuit slow response (bank 1 sensor 1)
meaning;;;one heater on o2 sensor is not heating fast enough or no heat.
look for o2 sensor heater fuse first
and connector wiring for rust
if ok change o2 sensor

Car made weird noises and then shut off while driving now wont even turn over

If the engine wont turn over after weird noises you may have seized the engine from over heating or lack of oil. Check for water in the radiator and oil in the sump. and if you are missing either then a replacement engine is the go

When i turn my heater fan on it makes a weird noise and vibrates, what is wrong?

My car did this and there was a mouse nest in the blower causing it to be off balance. Took the fan out and cleaned out the nest....all better.

Makes a weird noise when you turn the ignition to start. It has been doing this for a couple of weeks and now won't start.

That weird noise is starter gear clashing with the flex plate gears, change the starter and hope it works.

I have a 2002 Pontica sunfire my air condition stopped working a couple of months ago it doesn't even put cold or heat air, it makes a weird nosie, i was wondering what it could be?

If the weird noise is like a coffee grinding machine, the a/c compressor is shot. If the noise goes away when you turn off the a/c, it confirms compressor trouble. If there is a screeching noise when you rev up the engine, it could be that the a/c belt has too much slack and is not turning over the compressor. Heat production and management has nothing to do with the a/c, it is a separate system,

My volvo 850 making noise in left turns

You have a bad CV joint ... get it fixed right away or more damage can occur....and the car wont move if it does go all the way out.

well dude, it depends on what the shape the vehicle is in. i just bought a loaded 2001 durango 4x4 all power, black leather, heated seats...etc. i bought it for $2800. but its had 2 weird noises, (probably why i got such a good deal) one sounded like lifter noise in the engine that slowly went away for the most part when the engine heated up, it turned out i had an exhaust manifold bolt snapped off in the block. after a trip to the parts store, 60 cents, and 30 minutes i had the problem solved. then the other weird noise was a loud humming noise heard from about 20mph-80mph. some grinding when i turned, lots of clunking noise. thankfully my brother is a mechanic, he said it was probably a wheel bearing. so i went to O'riely auto parts, they wanted $237 for the whole wheel bearing/hub. so i went home and ordered one off the internet from AM autoparts, shipped to my house for $103 instead of O'reily's 237. and turns out it completely solved my problem, took about 1 hour to change. love the durango, drives good, sounds good, looks good. now i have a cruise controll still love the truck!
