Well guys, I have been thinking about switching my wiper arm myself since my onboard computer isn't able to cycle through the different modes by clicking at the end of the current wiper arm. All the other buttons, including the reset button, are working so it has to be a fault with the arm itself. I have found some DIY guides online which seem promising. However, I was wondering where would be the best place to find the part I need. I have search some local junkyards with no luck. I called my parts guy in Boston and he said the assembly would cost me $143.60. Any ideas or recommendations as to how to tackle this problem would be awesome.

Thanks in advance...

Anyone?!
