Yes, sorry. It was a while ago and forgot to update this thread.

Was the coolant temp sensor replaced? I read you replaced much of the cooling system, but didn't see mention of this.

The way the HVAC stops heated air during your overheat is super odd and not a behavior I'm familiar with at all. It does sort of sound electronic in nature. Usually this symptom ...

As far as the temp needle going low on the highway and coming back to normal in stop & go, that's a classic failed thermostat stuck open. Easy fix, just be careful to not strip the bolts.

My other advice would be to return/not install the Autozone ECT sensor. Use only OE parts for stuff like that ...
