So, I am going to assume that this additional climate control aspect is limited to the 40th anniversary edition and therefore, not included in the standard LC 97 EWD unless via a supplement that I do not have.

The very nice service bulletin provided kindly by ToyotaDon confirms that the part in question is a simple photodiode that conducts (low-resistivity) in light and does not conduct (high-resistivity) in low light. The cover is a dark translucent black, so likely it conducts only in bright light. I may use a light meter with mine and see at what level of light it switches.

I agree. It is much more simplistic than I thought. Do we have light or not simple. This was the state of 80/90s tech.

I am looking at my 1997 LC EWD Page-173 and there is no solar sensor on that page. This is weird. My AC circuit diagrams span pages 172-179 and there is no solar sensor on any of those pages. This is publication EWD282U. Can you please confirm that you are looking at the same publication?

I have access to the online service information through TIS, so it includes all updated information. The publication number has not changed though.

That is nice. I suppose that is an official Toyota or some type of paid service?

It is official Toyota and available a few ways, including as a paid subscription. My access is as an automotive instructor able to provide Toyota training to my students.

@Gerrha Anyone can buy a subscription to TIS. You can purchase time limited access for reasonable money if you want it.

Most of the service manuals in the Resources forum came from there.

May do that at some point, thanks.
