Air conditioner refueling - Toyota Estima, 2.4L, 1994

Because I bought the car in February, the air conditioner was not checked except visually.

And when summer came and it got hot, the kander stopped turning on.

It's good that there was a friend who runs the air conditioners.
He immediately said that there is a sensor that does not turn on the compressor at low pressure in the system.

The problem was solved simply.
I came to him and he took out a cylinder of monometers and hoses.
After a while, everything turned on and cooled.

I was selling the car already with a working Conder with a "new" engine and a clear conscience.
