How to Fix a Broken Car Air Conditioner's Internal-External Circulation?

[SanKing]

Open the glove box, remove the 7 visible screws, with the lower 3 covered by clip caps—pry them open to reveal; disconnect the audio cable clip. Remove the fuse box; there are two plastic rotating clips underneath—turn them and pull downward, then detach the entire fuse box. Unscrew the 3 screws of the internal-external circulation assembly; remember to unplug the motor connector before removing the assembly; extract the assembly downward through the fuse box position. Remove the three white screws on the motor to detach it; take out the white pin, replace the original broken baffle, and install the new internal-external circulation assembly.
