Sleeper fan don't work.

Hello
Volvo 780 2016. Auto but no ishift and left window is maunel. I have problem with sleeper fan. It wont turn on, lights and over head light works but fan wont turn on.
All the batteries replaced, blower motor replaced. When i forced it from the driver panel. It beeps. Then displays E01 for a while before panel shuts off.
Espar stopped working, now the sleeper wont blow. Have idle free that heater wont work either.
What can i do for the sleeper panel and the blower?.
Thanks.

 

Its the sleeper blower. Not idle free. Idle free installed on top of the cabinet. The fan switch from the sleeper panel. I checked fuses. Its not the fuses...

 

Yes. Those fuses are ok. Theres no blower fuse there. Beside the panel is off. It only comes on when i force the fan from the driver side. It just beebs then its off minute later. Usually displays the E01. I can only turn on ceiling light from driver side. I am not sure if the panel itself is the problem.

 

I need to remove the whole wall which includes speaker, tiny pilot light etc. Several screws. I will buy screw driver set and remove it to see.

 

I removed the the wall. Unplugged all the connections. Nope avail. Still sane issue. Even called volvo action center. She told me empty slot for fan fuse.
