Been there. Lost everything but high speed, wouldn't even park properly. Replaced turn signal component and everything was restored. Don't remember if the washers stopped too, but get the wipers working first and if the washers don't come along for the ride then deal with that.
Given the fact our units are distantly related ('04 Southwind) it seems to be likely fit.
