Been there, done that....Back in about '82 as I recall...Thinking like you I fixed the 'air' side up nicely, which isn't easy as the tube is part of the wiring harness, After much testing and dismantling i found out the of/on switching is a different mechanism to the delay switching, though they are part of the same switch(es). In the end I prized the cover off the contact sets and found they didn't have enough spring in them/ weren't lined up properly. A little bending with a small screwdriver to increase tension and I got it working. PS its heaps easier if you take the time to take it all out of the car...but that has problems off its own.
