1975 450 SLC

If I turn the air conditioning blower motor switch to the first position the 'fan' produces a squeel. It is annoying. If I increase the fan speed, the noise goes away. Sounds like a worn bearing or something of that nature. I'm wondering if there is a fix other than buying a new, $450.00, blower motor?

 

it is tricky to change the bearing but somebody did it and posted the procedure here before.

 

My searches produce post of members with similar trouble but no post about fixing the problem. If you happen onto it, please let me know.

 

just a try- if the dealer does this it will cost$$$$ i may think it is the little metal strap that holds the motor to the housing which also is only held in by one littly itsy bittsy screw- if you can take it apart to the point you are looking at the blower motor and you notice you can move any part of the motor/or fans you have found your problem- the strap which holds the motor needs to be made stable once again- look at previous posts for a really easy DIY afternoon project which is actually quite easy. benz of tucson wanted $1400- i did it for a 6 cent screw from home depot (now that is a screwing!) best luck, george
ps- if the strap is loose/broken the fans(I cant think of the work- the barrels/cages with fins that make the air move similar to fan blades on a fan) will rub against the housing making this sound
