Attention: TDR Forum Junkies 
Normally I’m pretty tolerant of most of the idiosyncrasies of vehicles. I learn to enjoy the positives and overlook the minor odd design and engineering “mistakes”, particularly those I can’t do much about.
However I discovered one not long after I purchased my new-to-me 2015 3500 last summer when I opened the electric rear slider window. Why, oh why, did the electrical group at Ram decide to make the switch work opposite the way the window slides when watching it in the rear view mirror. I assume all are the same – pull the switch to the left to slide the window right to open it and push it away to the right to slide the window left to close. Whaaaat??
Anyway, I don’t have time to think about it when driving and decided to fix it.
The switch is retained in a section of the overhead console that is about 4 to 5 inches wide and about 3 inches tall. Use a flat trim tool to pull it down on the rear edge and it will pop right out holding the switch. The switch can then be easily removed from this trim panel from the back side by squeezing a couple tabs.
There are 5 wires to the switch, on mine anyway – 2 on one row and 3 on the second row. The first two, a black and orange wire, are the ground and power wire, respectively, for the LED inside the switch to light it up inside when the headlights are on. The other turned out to be the main power supply (center wire, red with yellow tracer) and one each going to the window motor – one to run the motor one way to open the window and one to run it the other way to close (tan with black tracer and tan with red tracer. You simply need to swap the 2 end wires to change switch action.
I discovered the side of the red plug holding the wires swings open to help remove the wires from their sockets, however you still need a very small flat blade type remove tool to release the tiny locking tabs holding the female connectors on each wire from the plug.
Once you swap these two and plug it back onto the switch, the movement of the switch left or right will match the movement of the window open or close.
Snap the switch back into its small panel and snap the panel back into the console and you’re good to go.
Window wires, power in the center, left and right movement related wires on either side.
Ground and power wire for the internal LED to light up the switch when the headlights are on
Switch with wiring harness plugged in but with switch out of its trim panel. I've used masking table wrapped around the socket on the switch so I could write what wire does what on the tape.
Hope this helps someone else rectify this annoyance.
