Help finding a Fusible Link
 

Hi, I noticed that my Rear Window Heater was not defogging this morning (not yet frost and far from ice). I pulled the fuses and they we're fine. Is there a possibility that there is a bad Fusible Link? Alldata lists two but I can't locate them because the designation is 11E and 17E and I can't find these on the diagram under the cover.

IMHO check fuse 13P in the central junction box, as it directly controls the rear window heat. Those fuse links in the battery junction box control other stuff also I bet. See attached schematic from the LR3 shop manual, you can down load the whole set for free, it is not the RAVE, but I have put the source up in previous posts.

I just yanked the Fusible link for my Headlamp Washer Pump. Usually the Fusible Link fuses are located in the same box as the corresponding fuses. The Fusible ling fuses look like a taller square block fuse with a clear top. They are different colors depending on the amp rating. I doubt you have a fuse problem. If the light on the defrost button comes on, it is possible that maybe a connector got loose from the rear window or one of the little heat strands that run back and forth across the window got cut. (Any recent window tint work?) I know on my LR3 the rear window defrost isn't really visually noticeable unless the window is really fogged. I am sure you could test the connectors on the rear window with a voltmeter.
