My rear defrost isn't working. They light will come on and the fuse is good. Reading about other models, there might be a relay for this, so I thought I'd try that out. If there is one, does anyone know where it is located? I have a 2005 RL.

Also, I checked the rear window, and there doesn't seem to be any obvious issues, so I thought I'd try the relay and see if it's working, and see if power is getting to the relay. Thanks for any help.
