Fan settings not working correctly

Started having a new issue today with the fan settings (of course, when it's in the 90's). The fan still works normally, but the option to change where it blows from isn't working well. When choosing to have it blow out the dashboard, the air will blow gently from the dashboard as well as strongly from the footwells. It seems to work fine when I have to selected to just blow on my feet, or just blow on the windshield, but not just to blow from the dash. Fairly big issue at the moment, since it's regularly reaching the high 90's, low 100's around me.

I recently did some work in the engine bay cleaning the EGR. I had no problems during the service, and I don't think I messed with anything other than I was supposed to, but I mention it just in case because it happened within a few days of this problem. Advice on where I should be looking would be appreciated.

 

RESOLVED: Still no idea what caused this, but I fixed it in Techstream by re-initializing the A/C. Took about 10 seconds and is working normally now.
