Blower Motor scoping and interpretation

Looking at this capture of a blower motor would this be considered a bad motor ? Motor is pulling about 18amp on average and seems to be moving plenty of air . This car had a very dirty cabin filter causing a complaint of inadequate air flow from vents. Replacing filling made a huge difference however I decided to scope it just for my own records . 

would you consider this a motor with a burnt comm segment or a winding issue or is this considered a normal pattern for a blower motor ? 

It's, certainly, not very pretty but, if it works, it works. It's hard to tell a customer that a working motor needs replaced.  However, if the customer had a complaint of intermittent blower operation, I wouldn't hesitate to replace it.  This waveform looks, to me,  like it is on the boarder line of being a blower that could need a good smack to get started, sometimes.

 

Kinda with Chad on this one. Borderline waveform like that would probably get a recommendation to replace it.

YMM and previous experience would factor in. If I've replaced them previously, it gets recommended. If I've never seen one fail previously, maybe let it go. 

My thoughts exactly, I did have one that had a “dead spot” some time ago and the scope capture was very similar to this . I have a screen shot of that and will post it for reference
