Cold air draft at feet on pass. side

Was driving north with the girlfriend this weekend and she said the entire way she felt cold air blowing across her feet (I know..I know, I thought she was just complaining too.....). You could feel the heat blowing out but there was cold air coming in from just under the glove box. Was thinking door seal or hole that needs sealed in firewall?? Anyone ever have this problem?

Thanks for your time
Tony
