Couple of questions...
Did the Suburban door go onto another four door truck or did it go into a two door and you swapped over all of the switches?
If it's on a two door, you probably have either a short or a bad master window switch.
The window switches are hot and close the circuit when pressed to send voltage to a window motor.
So somehow voltage is getting to the right window when the left window is actuated. Look for the tan wire leaving the master switch, see if it is pinched and touching the dark blue wire feeding the driver side window motor.
Or, less likely, the connector at the master switch is reversed.
Otherwise, I would probably just get a new master switch.
