The wipers on my 1996 Peugeot 106 won't come on intermittently. Does anyone know if this is a big/difficult job to sort out? If I get a mechanic to do it, do you know what the costs are likely to be? Any help much appreciated. Thanks.
Could be the switch but most probably the wiper motor, a car breakers yard is your best bet (price a new one first).
A Haynes Manual will explain how to change the motor.
