hi i took the car to coin car wash to powerwash the dirt off before i take it to a soft cloth automatic carwash. the thing is, when i arrived the gas station i couldn't roll down the window (all four) lol. there's some water build up and it froze up enroute. hope i didnt damage anything. are the motors that weak it can't break a little ice? or was it designed to stop moving when it detects resistance.
