Best approach when going in after *any* problem is to check the cheap fixes
first. Your fuse blocks (one under the dash & another under the hood near
the battery) are easy to get into -- you can check for both what each fuse
controls (but sometimes it's a bit cryptic, like "Acces") and whether any of
them are dead. Next step would be the switch, although it's unlikely that
both switches would go at the same time. Before you swap out the motor,
check the relay (*probably* in the door near the motor). The idea is not to
spend money on expensive parts only to find that a cheap one would have done
the job...

Yes there is a way to check it, remove the door panel and see if there is
12volts at the power wire in both directions, you may take a small  hamer
and tap on the window motor while operating the switch to see if it works.
if so the motor is bad, replace the regulator assembly.
there is no fuse for one regulator only
