When the battery was re-connected it blew the blend doors. Pretty common problem.

Actually it blows hot with the air off, at all times once warmed up. I'll try your advice and lyk how it went. The actuators need to recalibrate is what I read somewhere but idk much about those besides changing fuse #39 should remedy it, I'm guessing that's the air compressor fuse. It had a freon shot last yr so prob not that
