Blower motor loud rumble noise??
Anyone else have a problem with the blower motor making a lot of noise in th 3 and 4 speed setting. Sound like a low freq. flutter or rumble...very annoying. Is this a known problem or unique to my car? I have 7500 miles and this just got loud today. By the way this is not the a/c noise, it will do it with the engine off, a/c off, blower only running.
