Rear defroster? My rear defroster doesn't work anymore. I checked the fuse and it is good. The connection on the back glass is good too. Can the actual switch go bad? What else could it be?

When I got my car the rear defroster did not work. Used car dealer said he would fix it before I picked it up, but you know how that goes. So I brought it back and he ended up needing to get a whole new hvac control for it, just because the switch was bad. If you press the switch but don't hear a click or see the light come on, it's the switch, which like I was saying is not available by itself. Rear defroster switches all operate relays nowadays, it is on a timed cicuit so that you can't just leave the rear defroster on indefinitely, because it draws enough power that it will eventually melt a connection somewhere. That happened to a 1990 Geo Prizm I used to have, which had a regular switch for the defroster instead of a relay.
