This can be a couple of things. You have a water valve item 12 in pic see if is passing water through it so it will be hot both sides. Then there are temp actuators on LH (shown second pic) and Rh they may not be working. But pull the hvac fuse for 60 seconds with key then reinstall sometimes these reset. Otherwise they may not be working.
