DESCRIPTION





The heater unit case "C" (see Fig. 1) was modified during 1993 model production. The modification eliminated a cutout from the case for cold air bypass to side vents.

MODIFICATION PROCEDURE

2. Make a copy of the template (supplied with the replacement part and shown in Fig. 2) and use the copy as a guide for the cutout.

3. Place the copy on the heater case "C" as shown. Refer to Fig. 1.

4. Mark the area to be cut.

5. Use a suitable tool to remove the area marked on case "C". Refer to Fig. 1.

NOTE:
If the unit is assembled, use care not to damage the dampener doors with the cutting tool.
