Sounds like the blower motor...at low speed it makes the noise due to motor or blower wheel out of balance or something in the blower housing

    That's what I thought at first, but as I said, when I turn the switch up higher it has no affect the noise stays the same. It also goesaway after a while, regardless of blower speed switch position.

    Well if its a badly worn motor or out of balance blower wheel it will kinda fix itself once it gets running..try turning the fan completely off before you start car...if the noise isnt there...then the problem is blower related...if its still there, check the belts for wear and tension under the hood.

    I just talked to a Technician where I work....He says he he's heard of an air pump that injects air to the catalytic convertor for cold starts that goes bad. When it goes bad it makes a fluttering noise like I describe.....Sounds to me he may be onto something.

SOURCE: 94 Jetta runs fine until car warms up then check

Check the injectors, as these are a electrical part when the engine warms they may fail, if you are familiure with your engine (i.e. fuel rail and injector plugs) when this happens (i would recomend somewhere safeto puill over) hop out and in turn unplug your injectors with the enigine stillrunning, if you unplug one and the engine tone/noise does not change you have found the culprit.

The only efficient way to indentify the fault is by getting the fault codes read from the on-board diagnostic system. Without that data everything is just guesswork.

However, an unusual ticking could be a failing cambelt which is "new engine time" if not rectified immediately.While there, check the alternator and hydraulic pump belts .

Hope this helps. If this "fixes ya", I'd appreciate a rating for my reply, If not, please delay the rating and add a comment with any extra info you have and I will try to think of something else.

Cheers, D.

SOURCE: where is flasher on 2004 2.0L vw jetta

you said that you bought a knew flasher. did you mean the relay or what? if it is the relay then if you turn on the flashes and listen you should be able to find where it is located at. usually it is located under the dash on one of the sides if not there then check under the hood by the fire wall.

SOURCE: 2001 New Beetle A/C fan noise

I think it is the cabin/ pollen filter. The noise is louder on normal AC operation cos thats when the air is being pulled in through the filter and the sound decreases with recirculate because the filter only functions for outside air.
Need to use a credit card or similar to seperate and move the upper dash centre piece towards windscreen, it clips off. Then open the 3 x torx screws and lift the dash on the passenger side. then remove the plastic cover (oddly shaped) it has about 7 screws, then twist and remove, it requires some real effort, then pollen filter is visible. replace filter and voila! it would make your AC perform like a new car again!!
Hope it helps, Yusuf Johannesburg-South Africa yusuf.ginnah@poynting.co.za

Blower motor thermal cut off


Obviously, you are talking about your vintage 1932 Chevy Coupe. I know that's the vehicle because you did NOT say that it WASN'T!

The fluttering sound is probably dry leaves that got stuck in the blower assembly! Suck them out with a shop vac!

I have a 2004 Jeep Grand Cherokee Laredo 4x4 with the 4.0L. It has approximately 150k miles on it. I started the Jeep with 1/4 tank of fuel in it and it started rough and acted like it was going to die....


long post.
ill reduce it for you.
misfires. (is RPM below 700 then misfire can be normal) for idle speed controls dead.
ISC the isc controls speed, of idle,.
mine stuck like zillion times, in 400k miles. endless.sticking
mine was a tiny gutless stepper motor drive ISC valve.
the cone valve is side gets nasty and sticks (
(PCV gases caused as seen on all engines)
i clean it.
the proof is the easy press of right foot easy raises idle back to 700rpm and engine stops misfiring.
ever get a tuneup this decade or running spark parts 500,0000 miles
for the new world record.?


now the tricky part of ISC, , fully explained in the SM serv. man.
the PCM learns its behaviors.
it learns all hot start settings and cold
so when you key on, it goes to the correct HISTORICAL spot.
if it can move there(sticks) engine car race.
or run too slow,
cold start would be worse, as hot isc is more closed
so if sticks there closed, the next cold start will be horrid
some newer manuals telly you to add 5% throttle if car is hard starting this is so common.

clean it. end story.

I changed my clutch and releasing bearing but the noise is still there. When ever i release the clutch the noise starts like the release bearing problem and when i take off in first and second gear there...


a release bearing will make noise when you push on the clutch, the input shaft bearing will make noise when you release the clutch, the transmission will have to be removed and torn down to replace the bearing.

engine is pinking,predetonation of fuel or the fuel mixture is weak which can be caused by a vacumn leak on the inlet manifold ,such as the take off for the servo ,or the manifold bolts loose.Also the timing is set wrong which could be a fault with sensor or the sensor drive ring .Without the car in front of me i cannot really diagnose a fault like this ,either get the VW mechanic to have a look and if he thinks its electronic then take it to VW

Lifter noise when on start up then goes away after few minutes


These engines did make a little rattle when first cranked. Are you running an ac/delco filter? i have seen a lot of engines make noise from cheap oil filters. they will let all the oil drain out so when you start it has to fill the filter back up before getting oil to engine
