Well, since the car seems to not want to return to idle with the A/C on, and sometimes with it off, I began to poke around. The microswitch on the linkage works, and the idle speed motor hums, but with the hose off, all the impeller thingie does is bomve back and forth about an eighth of a turn. Took it apart, and there is a major divot on the "commutator" of the motor. Put it back together.

I assume this is some sort of an air pump and should spin? Does anyone know for sure?
