Drove the car for the first time in 90*+ weather and traffic. The A/C wouldn't turn on either (checked the codes and nothing crucial came up).

Coolant temperature steadily rose to about the 5/8's mark. I picked up speed and the coolant cooled down.

When I got home, I noticed the "A/C Fan" was not coming on.
What can be the cause of this? A switch?

Also, where should the coolant temperature normally be? Mine seems to move around a lot in the lower half of the gauge.

Thanks!

Here is a bad picture of the car in question:

I'm guessing your thermostat is stuck partially open but it won't open any further. This allows it to look normal in normal weather but runs hot when it's hotter out. The AC will not turn on if the MFTS is reporting an overheat issue.

I'd replace the thermostat and go from there.

^ Definitely not the same setup as a coupe fan, but I ran into the same issue, it was simply a matter of wiring issues with intermittent connections, start there and trace back

i had the same type of issue with my urs4 and it was a burned out electric cooling fan. Not overheating, just a little bit warmer than you would like while sitting in traffic.

is the clutch fan good?
I took mine out just got the electric fan and it will run, even if the a/c does not work.
does the after run cooling work?
