Is the ws cracked or is it just leaking?
If it's cracked; try a pick and pull to find one; order a new w/s seal; AND either way, pay a good window guy to do it for you who has installed ws 's on older MB's
He shouldn't charge you more than $75.
They will do it right, with the proper lube...
no worries...
