Hi Friends,
 My power locks sometimes (most of the time!) get stuck when being locked with the wireless key fob.  They move a little bit then stop.  I expect it’s a bad or sticky solenoid, but is there any easy way to identify which one it is?  I expect, with my luck lately, it would take me 5 removed door panels before I find the offender.
 Anybody have a clever way to attack this problem?
