My blower motor went out recently and I replaced it. Now it seems that when I turn the blower on highest setting and when driving at 65 mph or higher there's a whistling sound coming from the vents. It's not extremely loud, but it is annoying. At lower fan speeds the whistling doesn't happen. Also, there's no whistling when at idle on highest fan setting. It's annoying and depressing, as I have no idea where to start to fix this new issue. Any help would be appreciated. Thanks.
