Miata A/C and Cooling issues with questions

[balactm]

Have you checked the timing?   Are you getting any pinging?

Are you sure your timing belt isnt off a tooth?   It would probably run like crap if it was,  but its worth checking.

( I know its not AC related,  but even if the AC was stuck on,  the car shouldnt overheat)

It's very much possible it's off timing and still feels alright. I had my cars all turned around and it felt better at the top end than stock. That'd be a good thing to check and would offer a chance to get his hands on all of the plugs and accessories and make sure they're plugged correctly.

If the engine has been replaced, maybe check to see if all of the cooling lines are ran in the correct orientation?

I followed the service manual getting the engine back in time, spun the engine a couple times to confirm everything lined up again. First time on a miata, but definitely not my first rodeo with a timing belt. There are no unplugged plugs. Car feels the same before and after timing belt. And Taylor, I was anticipating needing to change fluids, fiilters, hoses, etc; the car was only driven 12k miles in the last 12 years. But this seems to be more of a wiring gremlin type thing. God I hope they didn't feed this thing after midnight...
