    Sorry if this is in the wrong forum, I couldn't see if there was a place for HVAC questions. I also noticed that the air seems to be coming out of the dash, vents, and floors. Any thoughts, yall? I'm throwing no HVAC-related codes at all. Thanks for your time and help.

    A blend door is normally a cause of it blowing out of mulitle vents or just one and never switching.

    A blower motor resistor could cause the fan speed issue.
