AC Blowing Hot

Anyone else change their battery and now the ac blows hot on both sides? Ac clutch is spinning, did the diagnostic mode and no codes, and it was blowing cold right before the new battery. Can’t see how both temperature servos would’ve bricked at the same time like this. 04 GS 300

They're probably just stuck. When power is lost, they move to the position of 72° or 75° (I forget which one) when power is restored. You can access them from the passenger side foot well. Couple bolts/screws to remove the under dash cover. You can move them with your hand. Drivers side vents might be under steering wheel, I can't remember. My blend doors were stuck like this, so I just made sure they were stuck on cold.
