One of the interior pieces of a Shark that is particularly susceptible to looking "ratty" through age, use and normal wear-and-tear is the heater/air control assembly found in the shifting console. Surprisingly, this particular component is often overlooked when doing an interior restoration or refurbishment, and leaving it in its stock condition can seriously detract from an otherwise pristine interior re-do.
Refurbishing isn't difficult to do, thanks to a heater/air control refacing kit available from Corvette Central. Only simple tools are required and the refurb takes well under three hours total, including removing the control unit from the car, refurbishing it and reinstalling it.
The first thing you'll have to do is remove the heater/air control unit from the car, which is accomplished by removing the shifter knob and reverse lock-out lever (if it's a stick), then removing the shifter console plate which is secured by four Phillips screws, one in each corner. Lift the shifter plate upward and disconnect the bulb connector and the cigarette lighter connector. Next, remove the two Phillips screws that retain the heater/air control unit, unplug the vacuum connector after removing its securing screw, disconnect the heater/air actuator cable, and disconnect the fan control harness from the fan control switch; at this point, you can remove the heater/air control unit from the console. From that point, here's what it takes to make your Shark's heater/air control look and work like new again.
Now all that's left to do is to re-install the control unit in the car, reversing the steps used to remove it. Plug the fan control connector back on the fan switch, reattach the heater/air control actuator cable, plug the vacuum connector back in, and secure it with its screw. Next, plug the bulb socket and cigarette lighter connectors back on the control unit, and then secure the unit to the frame with the two Phillips screws you removed. Replace the shifter plate and secure it with the four Phillips screws, replace the reverse lock-out lever, and put the shifter knob back on. That's all there is to it.
