My rear defogger doesn't work anymore. The light turns on when I push the button, but the defogger never warms up. My thinking is that the relay is possibly bad as I've checked the fuse and it is not blown. There are a bunch of relays under the hood in the fuse box except there is not a description of which one does what. If one of these relays is for the rear defogger and you can point out which one it is, I will be most grateful. I worry the dealership will charge a lot for testing etc. And a few bucks for a new relay is worth trying first. Also, it is a Civic Si if that makes any difference.

You will need to repair the metal lines that you see running across the rear windshield. You can purchase rear defroster repair kits at most auto part stores or order than from sites such as ebay. Com. Its pretty simple to fix and relatively cheap.

You mean the little metal piece with the wire on it has came off of the glass? If so then it can be soldered back on or you can purchase a defrost repair kit which comes with special epoxy for this issue.
