2. Turn ON the A/C switch.
3. Turn the temperature control switch to MAX COOL.
4. Put in RECIRC position.
5. Turn the blower control switch to HI.
6. Leave in this condition for 10 minutes.
REPLACEMENT
NOTE:
- If a component has been replaced, add an appropriate amount of compressor oil (same as the amount of remaining oil in removed component).
