PWM help

Hi, I am new here and was wondering if someone might be able to help me with a question. My robot is homebuilt on wheels. I want to steer the bot with an electric window actuator (from a car) The motor turns much to fast to control so I want to use a PWM to slow it way down. My question is what size PWM do I need.(size =volt and amp rating)

Here are the specs of what I am using
~Sealed Lead-acid Batteries (12v12ah/20hr) 2 in series)
~Dorman 741-814 window actuator (Just the 12 volt motor!)
~DPDT switch wired for reverse to turn wheels left and right (servo attached to run remotely)

Thanks for any advice. Also if you have a better less expensive approch I will take any suggestions.
