Default H3 HVAC control unit

Hello everyone. If you've seen my previous posts, I'm having the lovely H3 issue where I move my temp one click from coldest and it goes all the way hot. I also have the same issue where if I move the mode control one click from full face level it goes all the way to full defrost. I replaced all of the blend door actuators, and it was working for a little bit but now isn't working again. I replaced the HVAC control with a pre-owned one that I thought was working, but is actually defective. I'm trying to locate a brand new HVAC control unit (part number 25920831), and am having issues finding any websites that have it in stock. Any recommendations?

To help the OP, can you confirm the 25925113 is a direct connect?
