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?

Alternate/OEM Part Number(s): 1573416, 15789898, 15912988, 25814719, 25920831,1573909

If I remember correctly this is the same unit used in the Pontiac Solstice & Saturn Sky?? Check it out.:confused:

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