Hi, I have a 2005 Impala. When the rear defroster is turned on, I get the light on the switch, but the rear defroster doesn't seem to work properly. The rear defroster will partially remove the "fog" on the rear window, but only within a 1/4 inch around the wire strip. It seems the rear defroster does not heat up high enough. It will not melt any snow or ice of the rear window. I have taken it to the dealer in the past to have it fixed. I can't remember what they did to remedy the situation. Thanks.

 

could be an interesting issue. Relevant, anyway.

 

Took car into dealer again. They replaced the relay for the third time, and still does not work. I give up on the rear defroster!!

 

theres a short or a break in the lines that are in the window
