Intermittent Door Controls

It drives me nuts when something is not functioning properly on one of my cars.  When something goes wrong, it is often the only thing I can think about.  I will lay in bed for hours trying to figure where the problem originated and how I will fix it.

My latest issue was the door control switch began intermittently working.  This was a bit of a hassle since I could not roll the windows up or down.

After some poking around, I discovered that the problem was simply a loose connection in the door harness.  A quick cleaning and greasing fixed all of my issues.
