I have experienced the same problem a couple of times recently. I have no idea what this might have been, but it definitely sounded like a leaf blower and it happened twice when engine was at normal operating temperature. At first, I thought the noise was coming from outside (somebody using the blower), then, when I realized it is coming from under the hood I stopped and checked. However, I could not pinpoint the problem.
Did you get this resolved and /or look at?
Please share your experience.
sounds like a defective blower module
depends on where the "squeaky sounds" are coming from. something could be loose, such as a hinge or something. if it screams like a banshee, then its the alternator belt, or the alternator itself. it all just depends on where its coming from
sounds like a bad blower motor resistor and or plug
sounds like you have a bad blower motor.. i just replaced one on my 02 deville for the same reason with the same symptoms
Sounds like the heater core is leaking its a big job probably best left to the professionals
Sounds like blower motor module resistor
Bring to a shop and have it scanned to determine problem
Call a vet now!
Possible loose exhaust pipe, check hanger clamps.
sounds like typical transmission problem
Sounds like a bad blower motor resistor block.
Sounds like there may be trash in there..drop the blower motor out,get the debris out, put it back in...simple job...
