Question about 1998 Buick LeSabre
Something is stuck in your blower fan. There should be a access door behind your glove box. Drop your glovebox down out of the way, open the panel, there may be a filter for you to pull out, clean it all out, and re assemble.

THIS NOISE IS USUALLY THE HUB. HAVE SOMEONE GO WITH YOU ON A TEST DRIVE. GET THE ROARING TO HAPPEN AT ITS LOUDEST AND GENTLY SWERVE THE CAR LEFT AND RIGHT. DON'T BE SURPRISED IF YOU THINK BOTH HUBS ARE BAD. LIFT THE FRONT OF THE CAR AND PUT IT ON JACK STANDS. PULL OUTWARD ON THE BOTTOM OF THE TIRE WHILE PUSHING INWARD ON THE TOP OF THE WHEEL. IF THE WHEEL MOVES EXCESSIVELY YOU FOUND THE HUB THAT IS NOISY. USING A MECHANICS STETHOSCOPE YOU CAN SOMETIMES HEAR A ROARING TYPE NOISE ON THE BACKING PLATE SIDE OF THE HUB WITH THE ENGINE RUNNING AND THE TRANS IN GEAR. TRY NOT TO GET THE SPEED UP TOO FAR ESPECIALLY IF YOU CAN HEAR THE NOISE AT LOW SPEED, YOU DON'T WANT TO VIBRATE OFF THE STANDS.

Remove the sight shield from the fuel rail. (it's the large plastic shield that dresses up the engine) As you stand in front of the car the alternator is located on rear left side. In front of it is an electrical connector to the MAP sensor. Remove it. Press the PCV valve cover down and rotate it 1/4 turn counterclockwise. It is actully on the intake manifold. Lift the cover, the upper O-ring and the spring from the housing. Remove the pcv valve and the lower O-ring from the intake manifold.

You might just need a fan bellt or serpentine belt, get an empty spray bottle mix a small amount of
dish soap and water, spray on belt, then start your engine if the noise stops just replace your belt.,
if it does'nt it could be another pulley or the tensioner pulley, then i would suggest removing the belt
and spin each pulley to determine which one is making the noise. if it turns out to be the alternator, you
will have to replace the whole thing. they don't normally sell just the pulley, and even if you can get one
requires special equipment to pull it off, if needed just replace it and save yourself time and trouble.
plus parts normally come with some kind of warranty. good luck!
