Title: humming noise from 2005 jazz
Post by: guest1302 on June 10, 2015, 01:35:48 AM

hi all. I've noticed a humming noise from my car over the past few weeks. the noise is present whenever the engine is running and is  more obvious after a journey.  the  noise is there, when the car is stationary, and  if the clutch is pressed down or not. if i slowly press the rear window heater, or try to raise the windows  when they are already raised.then the noise becomes deeper and louder. when i stop pressing them the noise goes away. when the indicators are on, the noise level fluctuates in time to the blinking of indicators.
has anyone heard this problem before? I'm thinking the problem is with the alternator.  although i have no problems with starting. thanks for any help.

Sounds like the change in noise is consistent with change in load on the alternator. Check the belt for fraying and if possible check alternator bearings though much less likely.
Good luck   :'(

it won't be a wheel bearing if it makes this noise when car is stationary - sounds like alternator belt or bearing
