For the solar not working my 1st suspect would be blower motor if old- works at high current but not at low. You say it was replaced, was it new unit or 2nd hand? Or it could be poor connection/dry solder joint in relay, wiring or DC-DC converter.
The flap positioning motors are common issue, wear particles build up inside with time and they start working intermittently, then stop all together with time. If you take them off, clean and lubricate they are fine again. But access is quite hard to take them out depending which one it is. Sometimes if they are not too bad going into basic settings and giving them full range of sweep couple of times restores functionality for a while.
