Mii Blower with Macken

On the history of my Mii passenger compartment blower : it had already given up completely last summer, then to function again reliably 3 weeks later. Now it is out of function again. I am fully aware that there are hundreds of amounts here and there on this topic. But the problem with my Mii has its peculiarities. Here my previous measurement results : – blower does not work, neither on level 1, 2, 3 or 4, no noises (neither before nor now) – affected S thorax (30A) : viewed OK, measured OK, nevertheless exchanged (without success) – glove compartment removed to approach the pre-resistance – voltage on the connector of the resistance OK, individual resistors in the part OK, – thermal protection is NOT burned – blower switch in the dashboard checked : switches the voltage on/off on the specified connector : OK – voltage measured on the connector of the blower : 11,4V (while the voltage of the battery =12,3V) the switch was on Stu What is left of it? Must it be the blower. Contrary to this, the internal resistance of the fan is usable 15 ohms. In case of a defective blower I would expect more than 0 ohms, or more Meg ohms. I think a little bit of the ideas go out. Is there a problem, what can not be detected with these controls and measurements? Since I have no usable current flow plan, I can’t get any further.
