Default Rear window defroster doesn't work

Hi Folks,
I check all my fuses, and they are fine, but my rear window defroster doesn't work.
I remember reading somewhere that film tinting prevents them from working, and if that's the case, poop, but I'll live. If its something i can fix, I'd like to try.
Any ideas?

Thanks in advance.

The tint has nothing to do with weather or not the grid works. Are you getting Voltage at the wire at the top of the strut? How about at the bottom of the strut? Are you getting continuity throughout the grid?

On mine it was because the power wire(s) had opened at the grid. Checks where it connects. Mine was broken right at the solder.

Mine was busted right at the connector from being flexed every time the hatch opened/closed.

Try unplugging your connectors and cleaning the connections. Thats all I had to do to get it working again.

Thanks everyone. I'll hopefully be able to check when I get home. Been pulling some long days so far this week.
I'll check everything, and do measurements of voltages if it isn't apparent in the connectors.
:cheers:
