Nice temperatures, that's what we are getting with the hack. Also without the Hack, we are getting different drivers side vent temperatures, 6-8 degrees warmer than the passenger side. Can check your passenger side vent right next to your screen?
Hopefully it was just a weird little hiccup. I would not be afraid of it happening again, because if its going to happen again, better it does it sooner than later. If someone is wrong you did not do it, you just found it. "Use that pedal on the right":LOL:
The top hose going into the heater core, is always the inlet. Trace that hose to find a spot you want to install valve. You can test your chosen hose by pinching it off and running AC b4 installing valve.
If the tire is seated against the rim it was aired up to get it that way. Most likely it has lost its air for some reason. Valve core may be loose, maybe valve stem? You could balance a flat tire, if you were so inclined.
