Hello everyone, hope you're all having a great start of 2026. I am working on a 2017 Kia Sorento, it's blowing warm "not hot" air on driver's side and cold on passenger side. I just replaced blend door actuators and still didn't fix anything, the heater core is very hot which means it's working. The blower motor is working fine, all blend door actuators are working and the ahvac control unit is functioning. Looks like someone has tried fixing the same issue on the car but wasn't successful. What shall I check?

so i’ve called around to a few companies online non of them can offer me general liability or E&O because i live in idaho is my best bet just trying to find someone local ??
