The wipers on my 92 300SL only work at full speed - ie no slow speeds and no intermittant. I have tried the relays by the firewall and they made no difference - it hads been suggested this could be a motor fault but this seemed unlikelyas the motor seems fine.
Does the motor have its speed regualtor integral to the motor itself ?

It has been like this since we bought the car last summer- but we have only recently begun to see rain here - now I need to sort it out

Does anyone have any ideas before it costs me a fortune ?

Thanks in advance
