'88-'91 are all the same
Two things will close the recirc flap. The first is engine vacuum, the second is servo vacuum. Read on.
Engine vacuum will close the flap in the off (O) and GaleForce (<<=>>) positions.
Servo vacuum will close the flap in the other positions when the dash button is pressed. This works with the key on two clicks (in the run position) only.
If the valve won't close from engine vacuum, you have a vacuum leak.
If the valve won't close from the servo (located in the passenger compartment) it is more than likely the AC fuse (#22 I think?) is bad.
Another symptom of a bad fuse is that the AC and recirc switches won't get brighter blue and brighter green when pressed, except in the engine vacuum positions.
My head hurts.
