Hey All me again

Now I have problems with left side rear window motor, it will not open.
When I use the up bottom any other door I can hear a little, click in these door's, does any buddy have an idea.

The motors do give up, sometimes they'll go again if you tap them (gently) with a hammer, but it's a common problem.
