The ign switch provides circuit 15 power to the blower regulator. And if I'm not mistaken, 15 for the main blower fuse as well. There are 2 or 3 circuit 15 outputs on the switch itself and the contact that provides power for the aac and wipers are the most common to wipe out, hence "jigglein'" the key.
