I just bought a used 03TL I've noticed the Rear Defroster barley works at all. It comes on, but it's hardly able to clear off the morning dew. Is this just the way they are on these cars? Or, has anyone had any experience troubleshooting and fixing them?

 

There are two things to check. First, see if it is plugged in at the top of the rear window. Then check the fuse for it to see if it's out or not.
