    I have a problem with lagoon airflow III. The airflow at some point started to work at full power and it cannot be turned off even after leaving the car and locking the central locking. Only the removal of the fuse causes the end of operation. I have the impression that a relay has hung up. Maybe someone met with such a problem

    Hello. It looks like a short circuit in the fan module, something like a resistor mounted next to the fan itself.

    Hello,

    did you solve this problem because it occurred to me today and I don't know what to do with it.

    I bet on a blower resistor or a climatronic panel.

    For posterity - the new blower resistor / resistor is PWM on the transistor and it just died for me. To get to it, you have to disassemble the glove box and look at the fan area. The resistance is mounted on two screws. Price on Alledrogo from 5 PLN - 200 PLN depending on what version of the car you have ;)

    In this car it is called a fan module, it used to be a common resistor

    Added after 4 [minutes]:

    Now the PWM module by using a transistor through which the blower current is controlled, and once a resistor, usually a few resistors

    Hello,

    I also had a problem that the blower blows to the maximum even after turning off the engine. Unfortunately, my version of the resistor costs from 250 upwards. Does anyone know if it is really possible to replace the transistor itself? I tried to find it to buy but it was nowhere available as a single piece.

    Hello. I have the same problem. Maybe someone knows how to replace such a transistor. This is the BUK 76010-55AL model. The replacements are JRLR2705 or BUK964R2-55B, if anyone needs them, because the original is no longer available, as is the resistor itself.

Topic summary

The discussion revolves around a persistent issue with the Airflow system in the Laguna III 2010 2.0dci, where the blower operates at full power and cannot be turned off without removing the fuse. Users suggest that the problem may stem from a short circuit in the fan module or a faulty blower resistor. Solutions discussed include replacing the blower resistor, which is now a PWM module controlled by a transistor, and the difficulty in sourcing individual components like the transistor (BUK 76010-55AL) or the resistor. Some users report high costs for replacement parts, prompting inquiries about the feasibility of replacing just the transistor.
