Hi, aida; From the cost, I'm thinking that you are referring to the wiper transmission linkage assy.? Usually, we have to go to the vehicle dealer for a new one, and yes, they can be spendy. Have you tried a salvage yard for a used assy?
On my Fiat Punto 2006 I have front right wiper blade broken. I have taken it to the garage and they said its full system that needs replacing and it costs about £250 but also needs week to arrive. They were not trying to rip me off and they suggested that if I can get Wiper Leverage on its one on ebay or similar it would do same job and it would cost about £10. My problem is where to get it. I have tried ebay but not sure what I am looking for ...
Please if anyone know how to find this part I would be very greatfull for help
