I'm having the same issue with my rear defogger....seems to be notorious with cav's and GM's crappy designs. I'm going to be investigating soon and I think this forum and my Haynes manual will be a big help, but I have a feeling it's that wire that runs under the drivers side carpet. Just another example of why I stated doing my own car repairs and maintenance - told a mechanic about the problem and he immediately told me I would have to replace the entire rear window!! Too lazy to troubleshoot it and just see's $$$.

Created an account to thank StevePT for the fix and Bryan101010 for the additional detail about wire colours. I was dreading having to pull all the wiring to search for a break, and was relieved to discover this crappy connector problem. Probably something that should have led to a recall notice, given the number of people who seem to be affected and the fact that a melted connector means the possibility of fire. But oh well. I'm just glad to be able to see out my rear window again. Thanks!

This really was a helpful post. Had to create an account because of this one. I never would have found this problem if not for this thread. Only the difference is mine is not corroded at all... it seems to have melted inside the plug where the purple wire meets the black wire. the rest of the wiring running through it seems fine. can i simply replace the connector? how can i go about fixing this? any advice is really appreciated!
