The other day, I noticed that the power window on the front passenger side door was very sluggish going back up after being lowered all the way down. Up till now, it has always worked fine to the best of my knowledge.
Engine was running at idle after a 10 mile morning commute; window on front driver's side went up & down normally so I don't think the electrical system voltage was low or anything like that.
Any suggestions as to diagnosis, possible fix, etc. ?
Thanks in advance :-)
