Heater Blower Motor making the chirping sounds at all speeds. Clears up at times, but suspect the motor needs replacing. I will pull it first and look for debris. Anyone have any brands they would recommend for replacement? I can get a little price break on Murray, locally, at O'Reilly. But Rock Auto has a few brands all close to the same price of each other, but less than the Murray. Guessing most, if not all, will be made in China. Have had luck with Murray products in the past.
