Extend Rear/Mirror Defrost Timeout

[Fizzy]

I've asked this in the Gen 4 forum, but didn't realize there was a dedicated Forscan forum here... so here goes.

Has anyone on their travels around the Forscan space found a way, or spotted a setting somewhere, to extend the timeout cycle for the rear window defrost?

This I'd really like to know. I timed this over the weekend and 5 minutes is laughable. Most other cars are around 30 minutes before timeout.

All I can find is F150 owners wanting to disable the rear defrost on remote start. I wonder if it's not programmable, and is controlled by a physical relay timer.

I came across the same. The guy didn't want it because he was out west and the powdered snow blows off dry vs. sticking when melted and wet.

I do wonder if there is a physical timer relay in the HVAC controls vs programming. It is quite annoying as five minutes hardly achieves anything.

5 minutes up here in the frozen north is a joke. It's enough to thaw the rear window, but then it freezes up again almost instantly. I need it on all the time.

And even when it isn't snowy, the other issue is in winter when entering my office underground parking lot. The side mirrors instantly fog up when I enter from the sub arctic temps outside, making it impossible to back into my parking stall.

I'm not brave enough to go start hacking random codes into Forscan, and without more people asking for it, we're unlikely to get our answer

I hope this gets some more traction. That is just simply not enough time.

I've resigned myself to this never being figured out. There just isn't enough of the right people (Forscan wizards) who care to figure it out.
