Temperature Dial

To adjust rear temperature dial proceed as follows:

1. Using masking tape, suspend a thermometer from head-liner so that bulb hangs at breath level over front passenger's seat and suspend a second thermometer at breath level between the rear roof outlets.
2. Position an auxiliary fan (24-inch blades) so that air stream is directed across air intake grille, close all doors and windows and set both front temperature dial and rear temperature dial to 75°F. Start engine and run at 900 RPM.
3. Make certain that all air conditioner outlets are open and adjust these outlets as follows:
   1. Front unit side outlets so that air is directed toward doors.
   2. Front unit center outlet so air is directed to top of front seat.
   3. Rear roof outlet diverter doors should be opened.
   CAUTION: Outlet air must not be directed toward thermometers.
4. Allow systems to operate for 25 minutes for stabilization and record readings from suspended thermometers.
5. If thermometers vary from the 75°F settings insert Temperature Dial Adjuster, J-21530 between temperature dial and casting and turn dials to coincide with the thermometer nearest the dial being adjusted.
