CORRECTIVE ACTION

Japan-produced cars: Lubricate the groove and shaft on the main cam link with the grease listed under REQUIRED MATERIALS. Replace the air mix control cable if it is bent.

Ohio- and Canadian-produced cars: Lubricate the groove and shaft on the main cam link with the grease listed under REQUIRED MATERIALS. If the air mix control cable is bent, replace it and the main cam link.

1. Move the temperature control lever to the full left (cold) position.




2. Apply a thin coat of the MH62 grease (see REQUIRED MATERIALS) to the slot in the main cam link.

3. Move the temperature control lever to the full right (hot) position.




4. Apply a thin coat of the MH62 grease to the now-exposed portion of the same slot.




5. Use a small flat tip screwdriver to apply a small amount of the MH62 grease to the shaft of the main cam link.

6. Move the temperature control lever back and forth several times to see if it now moves freely.

^ If the lever now moves freely, the repair is complete.

^ If the lever is still hard to move, the cable needs replacing. Go on to Air Mix Control Cable Replacement.

Air Mix Control Cable Replacement
