Hi there. Check the blend doors to the heater system. The doors could have a leak with the weather stripping. Then check the air ducting in the dash up by the heater blower motor and see if there is a leak for cold air to enter. The middle duct gets hot air first, then spreads out to the side air ducts. There could also be a leak where the ducts split off. If you need further assistance with the air ducts having warm air on the ends and hot air in the middle, then seek out a professional, such as one from Your Mechanic, to help you.
