Thanks For your input Raimund. I think I tested it with the resistor and
just listened to it run and it seemed fine. Hard to remember. Maybe I’ll
pull the air box again just to double check the blower motor since I’m in
there. Was trying to avoid going that deep since I just had the air box out
and resealed it all up two years ago.
