I don’t have any fault codes in the dashboard. I have changed the windshield wipers motor and now doesn’t work intermittently anly in mediun and high speed. When I start the engine windshield wipers start to work...

Thanks for the update. I am very surprised the wiper circuit is not workink properly and not throwing any SAM /chassis module codes which will tell us right down to the wire and connector pin that is showing a problem. On multiplexed systems like this one you can not always get away with replacing components without some reprogramming involved for the new component to be recognized by the SAM module. New switches and components can have different resistance readings and throw off the module or cause operational problems sometimes requiring the programming. For example here is a wiper code.
