There isn't one for that model.
An exploded view of the heater controls for a 1989 Olds Cutlass can be found in the Cutlass service manual. The manual can be found at most auto parts.
it's the idle control valve, $60 part, or the computer.
Like most cars. The heater control valve is located inside the closed compartment with the heater core and the and the AC condenser. It is a door flap that seperates the heated air from the outside air, or the AC air.
It is at the rear of the intake manifold, follow the heater hose. there is a flow door under the dashboard with a cable connected is that the control or does the valve body at end of intake still control it?
