Are both radiator fans supposed to come on when you have the A/C cranked?

The driver side fans seems to always be on, but the passenger side fan seems to not come on, even with the A/C on.

Yes, there is a low and high speed for the fans, but both fans should run at the same time. If you see one fan running and not the other, then there is a problem. Could be a bad fan motor or relay. Try unplugging that fan and using some jumper wires from the plug straight to the battery. If it runs then it should be good and the problem is likely something else.
