Pull out the heater box from under the dash, You need to disconnect the hose and cables to it and un bolt the blower motor to pull the box. The box is 2 parts and held together by metal clips. Pop the clips and the box comes apart, you will see the heater core.

You ssould replace the seals while you have the box apart. You can pick them up off of ebay.
