Most likely the cables. The flaps have fairly sloppy holes with just a heavy wire like shaft that holds the flappers going thru them. It is possible the shaft retainers could be tight or the rubber seal on the flaps could be dry, cracked or dragging.
Testing the wiper motor without everything hooked up is iffy. They can go like a bat out of ---- when sitting by themselves unloaded. As soon as you connect the components and particularly the blades, the extra drag is too much if the seals on the paddle inside the motor are worn. The motor will barely move if it does at all under those conditions and it will need the AC pump to get sufficient volume..
