WHAT does NOT work in your Supra? I have multiple.
There are soooo many systems that are incorporated in our cars!
I'll say about 30 systems that they come with,depending on the year and model.
Yes,a lot of it is electric/mechanical and the MK II's come with a PILE of 'em.
ALL of the wipers work,the CC works,the alternator works,the electric windows function,rear defroster,both front and rear latches,headlights,fogs,speedo, light,dash lights,cigarette lighter,console light,glove box light,seat belts,door locks,
A/C,heater,vanity mirror,dash lights,warning buzzers,headlight doors,back up lights,Tranny/clutch/diff/driveshaft,power brakes,hood/hatch struts,brake system,turn signals/parking lights,CEL light,door locks/alarm,door/hatch hardware,
electric/heater mirrors,lumbar support/seat adjustment,tunes, and the electrical list goes on.
Mechanical stuff is a completely different area.
I'll say electrical systems.
Our cars have a pile,AND THEY ARE QUITE RELIABLE.
Maybe we are so lucky to have so many systems that work.
30 KILOS of copper wire in our cars?
I'm not finished: sun roof,headlight washers,(A/T) overdrive,clutch switch,brake light switch,head light pop ups,OK,ignition/washers/wiper delay,trip computer,dash lights,glove box/console light,seat belt buzzer,rear hatch light.
I cannot think of all of the electrical functions that our cars come with from the factory. No way.
These do not work in my car:
I'll say, a lot ...more.
4: Rear hatch light.
5:1/2 of the dash lights.
6:Rear cigarette lighter.
7:Arm rest interior light.
Some systems that I'll never use/test:Passenger vanity light on the sun visor.
I'm trying to think from memory,at my desk.There are a LOT of electrical system that come stock,plus optional extras(on some models) that I cannot think of.
Engine/ECU sensors? Jeez!
It becomes overwhelming.
"Just look at the fabulous 'extras' on this car!"(Cheech and Chong reference.)
It's really is a large list.
The "P" type came with more extras/options than the "L" type,depending on the country that it was imported to.

My A/C leaked out years ago and as little as I drive it, just enough to keep the fluids circulating and maybe to a car show a couple times a year, it has just not been a priority to fix the A/C. I think everything else works, but then I don't test everything on a regular basis, like I haven't needed the windshield wipers in the last 20 years but every feature worked the last time it got used. Worst thing is really just leaky seals, I put scrap cardboard under the Supra to soak it up, but that seems to be par for the course on a 31 year old car. My 48 year old Corvette also the A/C has leaked out and it drips all over the floor too, but everything else works. They're for windows down, sunroof open, T-tops off kind of driving anyway.Phil D.

All those lights are probably on the same fuse, might wanna start there :P
The only major gripe i've got with my car is that the speedo is bouncy and inaccurate. Oil leaks? Yes, but that just lets me know i've still got oil flowing around in there...
I drove my car enough to start whittling down little issues here and there, the only things really not working are from me messing with them. I have not installed a harness in the CF hatch yet(even though the FBI sent me one) so the rear defroster is N/A and i removed the windshield sprayer system entirely when i installed a CF hood since i did not want to drill holes in it. No holes in the hatch either so no rear wiper, sprayer, or key. Also my factory brakes quit working on me, but that might have something to do with them sitting in a box after installing wilwoods. The factory spare also quit fitting over the brakes at the same time, weird right? I did get the dang power antenna going, gotta have those tunes. The factory ECU is about to quit working on me, something about not being able to work after you rip it out of the car and install a stand alone? AC works like a charm, just have to add freon once in awhile. I don't think it is going to work quite as well when i block the airflow with an intercooler though...

That list you named sums up most supras now:
not sure i've ever seen a rear hatch light due to just some dime lights. be on of the first cheap conversion i do Is adding LED's to every interior light.. and possibly some aftermarket ones for a more modern lighting inside so you can see.( like some small floor lighting attached to open door circuit)
haha wipers are pretty important, not that many drive these old ladies in the rain much.. I wanted to build a custom set of wipers so we could attach some new age blades in 2 minutes and not a 10 minute job.-Parker-

My dome light stopped working. I fixed it by cleaning the contacts the slide switch runs on. My heat didn't work but found that some dumbass had the computer unplugged. Same with my windshield wipers the computer was unplugged so they would work but then stay in the middle of the windshield. My cruise control has never worked I think I will try to fix it next. Not long ago my power antenna stopped working at all I've tried to look up a relay I'm sure there is one? My visor lights didn't work because the wire was broken off inside the headliner. I fixed that when I was doing some body work. My ac clutch was loud but worked. I lucked out with a used one off of eBay and haven't had any problems.
So where is that power antenna relay? Lol

A/C is the only thing inop on mine.
When I first bought it, a LOT of things "didn't work", but it was just a combination of blown fuses and bulbs.1985 5-speed "Ms. Swan"

I found the wiring diagram but not the location of that relay.
It hooks up to the power window driver motor control relay ,what ever that is.
