Window still not going down intermittently after microswitch replacement

[bg305]

Hello everyone, as the title says, my right (passenger side) window has an intermittent issue where the window does not move down the 1" or so when you pull up on the handle. It works sometimes and not others, when it is not working the red light on the interior lock button is also lit. I assumed (incorrectly) that it must be microswitch since it was intermittent. I replaced it, it worked perfectly the night that I did, but now yesterday it is acting up again.

Regulator??

I am also wondering if it is a connection / ground issue (since it is intermittent)

Thanks as always!
