Thank you, whunter. In fact I spent almost all day on 05/10 (Sat) to remove the blower motor. And, I did it! Now, are there any differences on the motor itself w/ or w/o pollen filter? I removed the squirrel cages and if I want to replace the motor only. Do I have to get a motor for "w/ pollen filter"? Or, a motor "w/o pollen filter" compatible?
