turn signal stalk issue... broken

[tzincp]

Hello,

My turn signal made one of those "interesting" noises while signalling right with the searing at center. Suddenly it will not cancel when signalling left and I have to hold it to keep it signalling right. :ah:

I see that in replacing it one can simply move the OBC lever onto a new switch assembly however my car is also equipped with headlight washers.
Would it be possible to simply replace the broken plastic peace from a new assembly rather than replacing the whole thing?

More specifically it sounds like there is a plastic nub in the assembly that wears down / breaks off over time (mine at 99K miles)
It sounds like people have managed to put tape on this piece as a shim- has anyone managed to replace it outright?
I have yet to take mine apart but considering the noise I suspect it is broken rather than worn.

Thanks
