1993 Toyota 4Runner '93 4RUNNER TAILGATE WINDOW

The tailgate window on my 93 4runner stopped going down the other day. It goes up fine by using the console switch, however, it won't go down. I can raise & lower it fine by using the key on the tailgate. Is this the Up/Down switch issue on the console or the window lock button (next to the up/down switch) not disengaging.

Thanks
