Both my vent windows don't work the voltage only reads for a second at the motor on 1998 Dodge Grand Caravan

I tested motors with meter when I pushed switch the voltage read for a split second is there a relay somewhere that controls them if so where is it or do you think it might be the door switch needs to be replaced. I am stumpte please help me if at all possible thanks.

Unplug the connecters and test the pins on the motors for continuity. No continuity- open in motor.
