You may have a bent fanblade inside your vents. This would be something that a mechanic would have to look at to know for sure but it may just be something simple. If you knew where it was coming from it could be more help.

Re: I have 2002 camery ,when I turn heat on, it works but...
Take off your glove compartment. you will see a slot for cabin air filter. take out the filter, stick ur hand down into the slot where the fan is, remove leaves. make sure ur car fan is turned OFF.

computer box will need to be changed,the computer is programmed to read the pick up sensors of the camry and is not compatable with the rav4,whiering harness needs to be changed to fit the rav4 computer aswell as the key code sensor around the egnition.
check wheel bearing...transmission output shaft bearing. noise is louder because when bearing slow down, they get louder from worn down ball bearing inside the cage, space is developing between the ball bearing..caused by lack of lubricate, or just worn out bearings
soulds like something is not write. jack it up and check it out.try to spin hub to see if you can find the scorce of the noise.there may be something loose.did you open a line in the back?or is your fluid level low?need to bleed the system.have someone pump the brakes 4 times and hold it all the way down.open the little fitting on the caliper.then tighten it back.do this until you see a clear stream of fluid.repeat on other side until brakes are tight.make sure keep fluid level up.
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,
If you turn on any/all heating/cooling control and it makes a loud noise, it is probably your blower fan; they are normally located under the dash (some vehicles are easier than others).
If it's just your heat though, not a/c as well, then someone else will have to chime in...
it has to do with the clutch on the cooling fan. I have had to have mine fixed at about 50 k and it is acting up again at 87k. This tends to go away on mine as the engine heats up.
