Climate-control connection

Hello everyone :)

Today there will be a short post. But this climate control was bothering me the most. I didn't know how to connect it properly, and I didn't understand how it should work. A huge thank you Mark79, he took photos and explained how everything is supposed to function. Also thanks to Pim25. He helped reinforce my knowledge :)

Half a year ago I was asking questions, here's the link for those interested in what the answers were: www.drive2.ru/l/9151309/

So, what is the essence of this. I will write in reverse order. The vacuum from the intake manifold passes through a vacuum diode.

It connects to the central branch. On the left side there's another branch, and hose number 2 goes into the cabin (the tube is insulated at the collector end, and regular inside the cabin).

Inside the cabin there’s a T-fitting. One end goes to the vacuum regulator (to the right), while the other end connects to some kind of solenoid located on the air conditioning unit block.

It's very helpful that it was clearly labeled where everything should connect.

Hose 4 also goes back to the vacuum regulator, and it’s marked too.

There is another hose number 3 among them.

It goes behind the engine bay panel.

And connects directly to a specific part of the heater vacuum valve.

This is how the vacuum regulator looks like.

The photo shows where hoses 2 and 3 connect. Hose 4 connects accordingly to the top.

Here’s what everything looks like in the end.

Yes, it's all terrible, I will have to tidy up)

It seems there isn't anything particularly difficult about the whole system. But mine was completely disconnected. I had to figure out from scratch. This is my first time dealing with such a system.

Regarding wires, this is probably the easiest part. The main thing is to place them where they are supposed to be inserted. Japanese cars have great protection against mistakes. If there are identical connectors, they paint them in different colors. So it's easy to figure out along the way.

In general, I've assembled everything, connected it all up, and it works :) The valve opens when adjusting the temperature closes)

Obviously, nothing would work without starting the engine. This is another story altogether. I mounted the fuel tank, connected the heater, filled with antifreeze, hooked up ECU and DMV. Started the engine — nothing. It spins. But out of 10 seconds that I crank the starter, around the second it slightly starts for half a second, then nothing happens again. No help from a boost either. Tried everything possible, reconnected wiring many times. All useless. Then asked a friend who's an excellent mechanic, showed him, and suddenly it started right away. Almost felt sad but also very happy)

He left, tried again — the same result. Started checking wires again. Never thought about this before, decided to check near the terminal.

There are many wires on the positive side. I have no idea what goes where, didn't have time to figure it out, but found a wire that was not making contact properly.

You can see it in the photo, directly inserted into the terminal. And miracle of miracles, the car starts with just half a turn of the key. Why is this happening? It's clearly plus and minus connecting and going both to positive. If anyone knows please let me know)

So now the car starts without any problems, and drives well too. I'm so happy)) Soon will sort out all these messes. Overall, this story reminds me of another similar issue with the pink one.www.drive2.ru/l/10319636/

And then there's the roof. Thought about writing separately but will include here)

Could not find rubber at all, and even if found it would be very expensive. Not an option for a student. Had to glue in glass. Advantages: holds extremely well. Doesn't leak. Easy to mount chrome.

Downside? Only one. It looks ugly inside.

Had to re-glue the roof with standard moment 88 glue, directly fabric to metal. Holds very well, also easy to remove without damaging the roof itself.

Due to weather lighting isn’t great :(

This is how it generally looks:

Even mounted a shelf for speakers already)

Now need to find rubber and glue around the edges to hide previous imperfections that were hidden by standard rubber.

So thanks everyone for reading, likes and comments :)
