Rear defroster fuse

On the 91 fuse panel, does the same 30A fuse work the power lumbar on the seats and the rear defroster? Fuse 12 I think? Switch is working. Connectors are on the struts ok, timer stays on about 15 minutes, but the defroster not working. Time to get out the old test light. Previous owner removed the tint film from the rear window (Don't now why) . Hopefully he did not damage the grid. It must be a Maryland idiotic law you can't tint the windows. He said he spent hours removing the film which made me worry since I can do it in 5 minutes with a heat gun on the outside.

Re: Rear defroster fuse

Probably the defroster elements.PO probably did the deed when he removed the tint. The switch has a big purple wire for power though, not sure if its sharing the circuit with anything.Its a big power robber.
