I don't recall the relay setup, but the solar power circuit in a D2 totally bypasses the hedgehog and all other controls and basically just connects the panel straight to the fan motor.
It really is a simple setup; I think Ian (IT) documented the retrofit here long ago.

I only really looked at the circuitry in order to fit a cutoff switch, which I placed in the earth side of the solar panel circuit. Easily accessible around the front passenger footwell.
My (failing) memory says that I thought the relay was actually in the HVAC unit, but it may be that it's an external relay and the HVAC controls it.
Either way, the D2 relay is in the more complex +ve circuitry, which is why I went for the solar earth for my switch.

I would expect (hope) that the D3 didn't "reinvent the wheel" so follows a similar pattern/logic.

My fan motor problems (currently not manifest) were equally evident in either mode by the way.

It's definitely separate relay on PF D2, maybe in FL they moved it inside AC unit.

Someone will have and be able to interpret the D3 wiring diagram; it sounds to me EXACTLY like the relay isn't switching.
That of course could be a faulty relay or a failing trigger signal (or wiring).

The solar panel is connected directly to J126 blower control unit. That appears to have a single connection to / from J255 climatronic control unit.

So "almost, but not quite, totally unlike a D2". I guess V2 is the blower motor and J355 the solar panel?
What is C20?

C20 looks like the solar panel to me, judging by the symbol. So I expect J355 is a DC-DC convertor (probably stepping up/down the solar panel voltage to provide a consistent, regulated output).

Indeed, I didn't look properly at the C20 symbol. Another level of sophistication over the D2, so probably almost nothing to learn from my/our comments I'm afraid.
