no not converting, i have been using my cordless drill to wind the jacks up and down on the van, so had this idea after seeing the motor on the new roller door. the motor on the door looks like a wiper motor. if a wiper motor is reversible i could use it on the jacks.

Agreed. Try it, nothing to lose. If it doesn't reverse, then it's got field windings.
With a field winding motor, if you can get access to the guts, reverse the field windings without reversing the armature windings and you can then reverse the direction.
Most modern wiper motors have permanent magnets.
