I would suspect the motor then - if you have a clicking sound then power must be getting to something so that rules out fuses/breakers etc so the problem must be with the motor....
Give us a call and we will sort the right one out for you - you may also want some door card clips (which we have) as at least half of the ones you take out will break (and we can also throw in a quick guide to door card removal and refitting
)
