[Solved] Peugeot 307 2.0 16V 2003 - Warm air supply is working / not working

Hello

I have a question, I haven't met anyone with such a problem yet, that's why I'm writing.
Namely, for a few days I was driving at full 28 degrees with the air supply on and it was so hot on average: on the driver's side, on average, on the passenger's side a little better. After a few days, only the cold air on both sides stopped heating. After a while, some flashes of warm air began to emerge from the vents again. The fan works properly because its blowing force reacts to increasing and decreasing the airflow level.
What's more, the car heats up to 90 degrees without any problems and keeps the temperature. The thermostat is also OK
The heater does not spit liquid, so I assume it's working.
I would like to add that when I had an Audi before, when I gave it full heat, I could not hold my hand in the airflow because it was so hot, and in this car I do not know how much I would have to hold my hand in the airflow to warm up.

Any ideas, why is this happening and it does not heat so well?
Thank you in advance for your help.
greetings

Hello. Air in the heater or there is a need for replacement, the coolant does not circulate fully throughout the heater.

The coolant was replaced because the entire water pump was replaced with a new one along with the entire agent.
After replacing this pump with a new one, everything was as hot as before the replacement, i.e. without changes. only now such problems have arisen.

Ps. How to bleed such heaters?

How do you heat the engine, have both 2 hot pipes from the heater, inlet and outlet?

I haven't been able to check that yet

I found this valve, the heater was not air-tight, because as soon as I unscrewed the cap, the liquid ran out.

PITERRR when it comes to these 2 hoses from the heater, both hoses are warm (not hot) after heating the car

Hello

I replaced the thermostat, the temperature inside the car changed. It is much warmer than before, but now I have a problem because it is much weaker on the passenger side than on the driver's side.
Cool air flows from the vents instead of warm air.
Any ideas what could be the reason for this because I don't know anymore ??

The air supply flaps do not work and the air flows from outside and not through the heaters.

As you think, just such a thing is enough:

whether to buy a used actuator:

Someone knows what the cube is there, I mean the number of pins. (because I haven't looked there yet)

First, undress so that you can see what is happening and then you will buy or order?

Do you have a manual how to get to such an actuator from the passenger side ??

A little update, I got to these modules. And both of the modules shown in the picture work properly after changing the heating.

The photo does not show 3 which is even higher. But if this is this module, which one controls the temperature, which one to turn on?

Hello again, today I checked all the heater's motor regulators and they all work properly, they are not broken or the tips are machined.

So it probably remains to replace the fuser, right?

If it does not heat up, check what are the heater hoses, especially on the return, if hot, then rather functional. If it is summer, there is no circulation to replace it or it is stony and heats poorly.

ok, next week i will start replacing it, let you know how after the exchange.

Because when it comes to the temperature of this two-tube, both wires are equally warm (at least I think so)

The replaced heater with a new twin-pipe that goes directly to it. The heat returned
