Wipers go down instead of up

When I turn my wipers on they go down instead of up. And when I turn them off they park at the top, so everything works, just backwards.
Is this a linkage problem?
Its a 3 speed motor on a 70 e body.
Thanks

Sounds like the linkage is connected to the motor wrong. Remove the top screen on the drivers side, remove the clip holding the linkage on (dont lose the washer) manually put the wipers parked, then connect the linkage and see if that solves it.
