Replaced blower motor, old one ceased. Also replaced heater matrix while everything was almost out of the way.
Encountered some problems after finished the job, unpleasant noise coming from blower motor fan.
Undo the new motor and found out that fan propeller was touching to wall in front of fresh air filter:
Fan propeller touch that inner circle part
Marks where two material contacted
Solved the problem by removing material from that wall part about 1 mm by rubbing with sandpaper.
Needed couple of tries before it was perfect.
If I need to replace blower motor later on, I'll definitely test clearance by pressing hard on each screw base holding the motor to it's chassis, shown in pic below, with my thumb while motor in place and running.
It will tell immediately if propeller is too close to the wall..
