what age is your almera? mine is 2003 and has the same fault that the wiper's do not stop until ignition turned of. I cannot find any relay's around bonnet catch, mine are placed under the bonnet, on the driver's side seem's all the relay's but the wiper!!!!!. The point that the wiper,s reset themselve's each time the ignition is turned off point,s toward's a relay sticking, but where are the Bl****y relay,s. Sorry about that, but have spent a lot of time and effort on this to no avail, hoe someone can help.
