It's really not advisable to simply 'up' the fuse rating if there is a problem causing the original 10amp fuse to blow (I assume 10amp is the original fuse rating). The fuse is there to protect the wiring and prevent it from overheating and/or catching fire. If there is a fault, either in the wiring itself or if the motor is partially siezed causing it to draw excessive current then the fault needs to be found and rectified. The 20amp fuse may be rated higher than the cable (although I don't actually know what size the cable is though) and if that is the case it'll just sit there quite happily while your wiring or motor overheats/burns out.

Are the wipers going slowly or seem to be struggling at all?
