CMS (Chinese Mini Split) Blower fan failure? Now E02 voltage error?

I need to open up the inside box for a look? But anyone have this?

This unit has sat unused most of the Winter other than using it as a fan intermittently and for actual air conditioning a few times in the past few weeks and it ran and cooled fine. I was using the unit yesterday for the fan mostly, setting the temp higher than ambient in the van so the compressor wasn't really kicking in. The blower started making some noise, then sounded like it stopped spinning. I turned the unit off, after a while turned it on, same thing, noise then stopped blowing, went silent.

Just now I turned it on just to listen to it to better describe the noise in this post and now I just get an E02 on the screen, won't turn on?? I believe this is a low or high voltage error?? My voltage on my bus bar is 14.2v and that's not unusual and it's run fine before now at that voltage?? I'll have to put a multimeter and measure at the power connections in the unit I suppose?

Will post updates as I explore this issue! Thanks in advance for any suggestions, tips, and hell, sympathy!
