I just replaced my drivers side air vent ( near A pillar) as the previous owner had swapped it out for a turbo gauge, and on the bottom is a clip where a wiring connector sits. The one on the new one had obviously been cut off, but I found the matching wires ad plug and clipped it on. My question is, it this supposed to be connected to something? I'm assuming yes, but can't see any likely suspects nearby.
My A/C isn't blowing cold either, and I'm wondering if this may be linked.
