The shaft is broke, and does not seem to turn, but the 2 pins usually mean
its a push button type.

This post shows the exact board so that must be what it looks like https://www.reddit.com/r/AskElectronics/comments/15bfj2i/volume_control_from_my_older_1996_chrysler_town/

The comments say its an EC11. Not sure how many detents, 30 maybe?
