BNR32 Rear De-Fogger IN-OP

[RBDev]

Greetings all, 

first post on here and am new member, but I have. 94 BNR32 here in japan and i recently replaced my tachometer due to it being Inop. After putting everything back together the tach works now, but it rained the other day and rear windscreen started to fog up, hit my de fogger button as it worked a few weeks before taking dash apart and now it doesn’t turn on.. the little orange light doesn’t come on and no power goes to grid..I’ve inspected all the grids on the glass and no broken grids.. 20 Amp fuse in the cabin fuse box it good(replaced it anyways), disconnected battery, and reconnected, took dash apart again and ensured the connector that goes to defog switch was plugged in correctly, no frayed or broken wires. My guess now is there is another relay somewhere hiding under the dash that must have gone bad somehow? Scoured all over the web to find a cabin wire diagram but can’t find anything. Idk if there is another fuse in the circuit I’m missing or relay that is bad but I am getting frustrated as my rear fogger is quite important in the humid climate here.. please help. And thanks in advance Godzillas!!!
 

p.s. Photo is just showing button in on position but no light on.

p787 of the workshop manual shows the wiring for the switch and p788 the defogger itself.  You would need to trace through but the p787 stuff will help you understand if there is a problem before or at the switch
