Reinstall in reverse order of removal. Note the following:

-- Check the insulation -E- in the evaporator housing -D- of the heater and A/C unit for damage, contamination (odor) and the correct installation.

-- Check the connection locations between the air intake housing -C- and the evaporator housing -D- of the heater and A/C unit (groove/ spring connection) for damage.
