Can one 12v adapter run three wiper motors?

Question

i need as little wiring as possible, hence the one adapter, each motor works fine when i wire them seperately but nor together, is my wiring bad or is there not enough output to power all three?

Answer

If you look at the label on your adapter it will say something like 12 V 350 mA. That number 350 mA means a little over 1/3 amp, and I would expect a wiper motor to draw between 1 and 3 amps. You need a battery charger to run even one of them.
