Help troubleshooting aux fans, late W124

I recently noticed that my right aux fan is not coming on. The left one seems to work fine, coming on when a/c is activated. Here in Socal, the car never overheats but when in 100F degree Las Vegas weather in traffic, it gets close to 115+ on the gauge.

My main question is, are the fans supposed to both come on simultaneously and run together? Or do they operate independently?

And is it likely that I just have one bad fan?

Thanks!
