I have just changed my wiper motor on my corsa c 2001. You have to remove your wipers, remove some of the bulkhead under the bonet, a couple of bolts hold the motor to the bulk head with a bolt also going into the bulk head just to line it up. It took me half hour once i had the wipers off as they seaze on. put some wd40 on the day before you start
