Why?

cant be normal. Check in to see a motor electrician.

Probably water contact with the wiper sensor or module. Pull it out and wipe dry it should stop. Noticed this in Peugeot 505 car back then. Leaving it wet can damage such module.

Lexusgs: Automatic wiper module, trying to wipe the underneath of your car clean !!!!!!
NB : You should sell this idea to Toyota

they come one when he passes a pool of water not when few drops drop from the above


meaning there is a naked wire being made to complete a circuit, water being the conductor
