M1165 Rear AC Rattle

Trying to identify this rattling noise coming from the Rear AC unit. The overall front and rear system blows cold and compressor runs fine. No leaks.

Think it’s the blower motor? If so, can that be replaced without disturbing the refrigerant lines?

See video for example of the noise:

It could be one or both squirrel cages are loose, or there is some crap floating around in there or the bearings are gone in the motor, you are going to have to unbolt it and turn it over to see, I think you should be able to fix it without disturbing the lines if you are careful

I unbolted it and lifted it to look underneath and it would only go up so far before putting too much stress on the AC lines. I blew some compressed air through everything to clear out some residual dust but was not able to tell if anything was broken. AC system is tight and full, so I want to avoid causing a leak.

Has anyone opened one up to replace a blower or squirrel cage?

Tip it forward instead of to the side. You should get some more clearance to get at the blower assembly. Pull it out and go from there. Its basically the only moving part in there.
