No rear blower motor after resistor replacement!!??

[500LiterMin]

Rear blower motor only had high speed. Replaced blower motor resistor with exact part # and now I have nothing. Even when old one is put back in. Is there a fuse to check? Or another issue?

UPDATE: So randomly it turned on full blast. Still the same issue. Quit working on my drive but after trying to turn the fan with a screwdriver it started going again. Another odd thing that is happening like it happened a year or two ago is that when you try to adjust the speed for the rear fan on the center infotainment system it will change the rear fan outlet setting. So if you have the rear fan blowing through the overhead vents, then adjust the rear fan speed on the main infotainment system it will de-select the overhead vents for the rear. WTF. This was only fixed after replacing the APIM module. Took like 5 weeks.
