Help with cooling fans.
 

2000 S here. Getting a new coolant tank and AOS installed as I type this. On the way to the shop, it was running hot. Coolant level was fine.
I have checked the fans with the Durametric software and they both run on low and high. Doesn't seem to come on with the A/C. Any idea why it's not kicking on the fans? Sensor? Switch?

Thanks!
