DESCRIPTION
When the vent mode lever is in the Face-Floor position and the blower is in the 3rd or 4th speed position, only a small amount of air comes out of the center vents.
This condition occurs only after the vent mode lever is switched from the Floor position to the Face-Floor position while the blower is in 3rd or 4th speed.
If you encounter this complaint, follow the Repair Procedure listed below.
REPAIR PROCEDURE
1. Set the mode lever at Defrost position.
2. Referring to the illustration, remove the mode wire from clip "A" which fixed the mode wire.
NOTE:
Be careful not to bend the mode wire when removing it.
3. Align the set pin hole at "B" area of the link and the matching hole of the heater unit. If a pin (0.24 in. in diameter) is available, insert it to fix the link to the correct position.
4. Verify that the mode lever is in Defrost position.
5. Set the mode wire to clip "A" as shown. Keep natural tension of the mode wire. (It is all right if the mode wire is slightly pulled to the direction "a.") Push areas "b" and "c" simultaneously when setting the wire to the clip.
NOTE:
Do not push the inner wire of the mode wire when setting. If pushed, it may result in deformation of the wire and prevent the correct setting.
6. Check the function of the mode lever. If the result is NG, pull the mode wire by 0.08 in. (2 mm) in direction "a."
7. Confirm the function of the mode lever.
8. Remove 0.24in pin if used.
