Hi, the fans are not working but I have seen a small switch that's not in place that makes them come on, but I can't find where it goes.

Yep, that is broken. I can tell where it is from the picture, I guess it is a heat sensor for the radiator? Check the image below to see if this could be the part?

If your about I send another pic looks like there is another sensor there maybe a replacement but still the fans not working, is it still okay to drive for now if not stuck in lengthy traffic?

I wouldn't, in the summertime the engine can overheat quickly. Dees the radiator cooling fan come on with the A/C? If not, you may have a bad fan motor. Here is a guide to check for power and how the cooling fan system works in the image below. Check the power to the main fan control module (fuse 3, 50-amp fuse panel A).
