Noise When Shutting Off The Engine

[is300yank]

Has anyone ever experienced a strange noise (low buzzing) from the front of the car (engine compartment perhaps) after tuning-off the engine? It seems only to happen after driving with the a/c on and lasts for maybe 15 seconds.

Also, does anyone know if a fan is supposed to come on after the engine is shut-off if it has reached a certain temperature? I'm thinking this sound could be a bad fan motor, if one exists.

Many thanks in advance for your consideration.

ya ur fan stays on sometimes after shutting down to cool the car down

yup ... there is a fan motor .. that comes on after the engine is shut off to prevent overheating of the parts. the timing/location sounds very much like somethin related to the cooling fan. u should check it out .. if somethin is loose or similar.

Thanks guys. The car is still under warranty, so I'll take it in.
