Front defroster relay/fuse location
 

Hi !
I removed all climate and AC stuff in my Z (and Navi) and rear windshield is lexan. But I would like to keep a switch to use front defroster.
On the OEM panel (Bose Navi) there was a button for the rear and one for the front. It should be running to the BCM but I can’t find wiring details. There are lot of threads about rear defroster but nothing about front which is more important (except if you drive only with R gear :) )
Does anyone have any info about the wiring of the front windshield defroster ?

No one is using the front defroster ?

Wiring diagrams, connector pinouts, wire colors, etc are in the FSM - link in sig.

Yes I already checked it: «*DEF*» document. But it is only about rear windshield and side mirrors :(
I don’t know where to find info at this stage

It will be in the FSM section about the cabin heater and air conditioning. IIRC, it's called a defogger (but wouldn't swear to it).

Oh it is just air ? It is not like the rear windshield (heated lines) ?

Yes.

FWIW, most systems nowadays will run the A/C compressor, cool the incoming air to dehumidify it, and then warm it back up before blowing it on the window(s).

Thank you so much for your time
