Read the first linked article, it shows good pictures of what a failed 
slide jaw looks like, and walks you through replacing one the easy way.
It's not particularly fun to do, but much cheaper than buying a whole 
regulator, and shouldn't take more than an hour or two, especially once 
you've done it the first time.


Here are a few links about the sliding jaw.

I haven't had to work on the windows on my SEC as yet, but from looking 
my car up in the EPC, it looks like the SEC's use the flat jaw just like 
my SD did.

Following the guide linked above, I was able to replace a pair of these 
sliding jaws without needing a punch to secure the new jaw, though a die 
grinder or drill makes removing the old one much easier.
