Hello there. Fan operation may be due to engine failure. Is the engine warning light on on the screen.?

The engine fault light does not come on. As I said, when I start the vehicle, the fan turns on and stops when it stops.

If overheating is not an issue, the fan relay may be faulty. Check it first.

thanks, let me have a look at the fan relay. They told me the electricians are from the brain. I don't think anyone looked at the fan relay.

If the fan relay and the sensor are the same, they said the switch is solid.

Is the relay switch all intact?

So they checked the relay? Because the relay may be stuck in closed contact mode.
Of course, it's the ecu that commands all of them. If they are sure of the relay, it is likely to be from the ecu.

If they said

brain, get well soon. I advise you not to believe too much.

These two words are very dangerous in industry

1- he is doing it from the brain, brother
2- the engine is fine brother, you can't tell what's going on until you open it

when you hear these, you say ok brother and go away.

1 year ago the car did not start. I think the immobilizer was locked, they worked in the industry for 1 week, last time I said they canceled the immo. I gave the electrician 400 to the brain engineer who canceled the immo, the car started, but the doors did not lock automatically, they said, again, they said from the brain. They said if we put on a new one, they said 1000 liras, we waited until the evening, it was evening, brother, I took it out, he said 500 lira, brother, we put a new one. I said, why did you not tell us, we waited here until the evening. Brother said it was my fault, anyway, we gave the 1000 lira. Tell me if you have a piece or I don't vouch for anything when you get out of here. said. Later we realized that the immo is not activated, the air conditioner does not work. The fan is constantly spinning and the brain on it is the brain of another vehicle with automatic transmission (mine is a manual gearbox) and I wanted to tell about this incident that happened to me, my own box, etc. Frankly, I hesitate.

friends, my problem continues. No temperature, no malfunction lamp, when I start the engine, the fan is activated at the 1st level, and when it stops, it stops.

I have had 2 fan problems before, but of course, there is no rule that my problems will be the same as yours. just to keep you in mind.

in the first; The master who pressed the air conditioner gas also leaked air into it while pressing the gas, so the fan was running. After evacuating the gas in another air conditioner and putting in new gas, the problem was resolved.

In the second; The engine oil flowing from the engine cover and gaskets caused the fan to run by sending a false signal to the brain, as it spilled and damaged the signal cables of the intake manifold below. It is very important to come across a master who knows his job.

thanks, since the air conditioner does not work from the brain, the master said that the air conditioner switch was directly installed by the master, because your fan was running continuously, then we inserted the key and stepped on the gas.
I think because the brain did not see the air conditioner. maybe the air conditioner detects it is working and runs the fan all the time
