    You can replace it quite easily as it is accessible from under the hood - they are available at most auto parts stores. What caused it to happen? - the bushings in them wear out causing the squeel.

    There's a small hole in the end of the motor, a drop or two of oil in there will get more life out of it. But yea its very easy to change out.

    lube er up!.

    I've drilled a small hole in the end cap of the motor where the bushing is under the hood,and used a oil can to squirt some motor oil onto the bushing..this works for a awhile,then the motor will squeal again sooner or later..I got 16 years out of my howling heater blower motor in my 74 K20--just had to add a few drops of oil every fall--I never bothered to change it--it still worked!--if it aint broke I dont fix it!..:crazy:
