4. Inspect the housing for correct degree marking (B) (Fig. 2).
The marking on the TCM should read:


31(5)F or 32(3)F


NOTE: These numbers are to be read: 31~F +/- 5~F (-1~C +/- 3~C) 32~F +/- 3~F (0~C +/- 2~C).

5. Replace the temperature control module if it
DOES NOT read: 31(5)F or 32(3)F and proceed to Step No. 6.


6. Start the engine.


7. Activate the A/C system.


8. Inspect to verify that the A/C system is operating properly, and that the evaporator icing condition has been eliminated.
