My hazards do indeed work, just not my blinkers. I did verify that the blinkers are not working. When I activate either blinker, the cluster indicator lights are not coming on, and the blinkers themselves are not blinking either.
At least that means that the distribution wires, including the turn signal switch and grounds are in fact functioning.
Very common for a ground to get knocked loose here or there, but if that was the case then the hazard flashers would not work either.
Now, if they were dim or of inconsistent brightness, I would still suspect a bad ground.
The fronts ground on the body at the core support just behind the headlights.
The rears ground to the body inside the tail light housing.
When I installed my AC vents, I'm wondering if I knocked something there
Very possible. You said you bought new flasher units? Just for giggles you could swap them to see if you just happened to get a bad one. It's so common these days that it's almost the first thing to check even though you had the problem before.
But a quick check too, would be to see if there is power in to one side of the flasher unit for the turn signals. If not, then the source got broken. I can't remember if the power comes from the headlight switch (like it does for the brake lights) or has a fuse.
I'll check when I get a chance, but maybe someone can chime in before that.
Good luck.
