Most likely cause is a bad vacuum check valve in the vacuum line that feeds the heating system. That check valve is located on the passenger side of the intake and should be within a few inches of the intake. Pay attention to it's orientation so that you don't put the new one on backwards. (It's a one-way valve.)
