Strange rear window defroster behavior

[Alex]

Getting the first part out of the way:
1988 Mazda 323 SE sedan us/non-ca sohc 2wd

All the horizontal grid lines heat up, but only in the vertical center third of the window. So, the center clears from top to bottom, but the sides stay fogged.

Sounds like a trace is not making full contact. Inspect the traces for breakage.
