Hi All. Looking for some help diagnosing a problem on a "new" (used salvage) door I just put on my 07 Commander. Put it all back together with my old door panel and everything works - except the driver's window. Rolls down fine, but when I try to raise it, it only goes up about a half inch at a time. Even if I help it along by pulling it up, it maxes out at 1/2" intervals. Is this the TSB re-programming symptom or likely a failing motor? TIA.
