1997 Villager Blowers....HELP{!!!)

I have a 1997 Mercury Villager and both blowers, front and rear are not working and went out at the same time. It would appear to be a fuse or relay but I have checked all fuses that I know about and cant figure it out. Anyone know what it could be and a remedy ???

both went out at same time? if so reckeck all fuses and
test your relay. check for good connections and good grounds.
