These show the location of the heater core in some year close to 93.
Access means removing the hush panel under the dash and the glovebox with its hinge. Someone had posted these pics of a car with whole dash out and I thought they are pricesless for showing someone how it comes apart. The programmer for the dual A\C sits on the corner of the plastic where the prongs stick out at 45 degrees. There's a small motor connector on top of the programmer, a metal link that snaps into the plastic connector and moves a vane inside the box at the bottom of the programmer, vacuum lines which might not have to be removed, and a large electrical connector.
