Heater-Evaporator Unit Overhaul

Overhaul
1. Remove the A/C thermostat, and pull its sensor loop out of the evaporator fins.
2. Remove the self-tapping screws and clips from the housing.
3. Carefully separate the housings, and remove the evaporator covers.
4. Remove the expansion valve if necessary.
Assemble the evaporator in the reverse order of disassembly, and:
- Install the expansion valve capillary tube against the suction line, and wrap it with tape.
- Reinstall the A/C thermostat in its original location.
