Use your fingers to pry and remove the red and white connector retaining clips from the harness connector. This will separate the connector into three individual connectors.

The three connectors are stacked on top of each other. The order from top to bottom is:

Defrost coil thermal fuse (yellow connector with two red wires)

One end of the defrost coil (yellow connector with brown wire in the left pin)

Evaporator coil thermistor (white connector with two yellow wires)
