Did you buy the motor from the dealer or online?
You should not be able to move anything by hand with a proper working system. The new motor is broken.

I will try to hook everything up again tomorrow, maybe I didn't get something clipped in enough? I just don't understand why both motors turn clockwise and stop as soon as I turn on ignition when controls are turned off. And even when I try to turn to heat or AC they wont move.
Have a good night and thank you so much for all the help.
Sorry to be a pain

Yes the linkage will move without the motor attached but once the motor is attached you should not be able to move anything at all.
When you attach the motor you are supposed to move the levers to accommodate the position of the motor when it is attached to metal socket on the underside.

And there are stops on the underside of the motor, so they do not go too far one way or the other. on the old motor, the large gear inside (yes I took it apart to see what was going on) was broken in two. when I plugged it back in and turned on the key, the motor just spun counter clockwise no matter if controls were off heat or ac

yes, I bought the replacement before I tore the dash apart.
I removed the old one, installed the new one and before putting everything back together, I took your advice and re connected the battery and started the truck. The motor turned counter clockwise (with all of the controls in the off position) I then turned the control to heat-no movement, then to AC nothing.
I turned off key, disconnected the battery and removed the new one. did same thing with old one. same results. then took the to screws that hold motor in place out, and I could hear (the old one "humming" so I took it apart and plugged it in and as soon as I turned on key, it just kept running with all controls off

That makes it easier. Getting in and out of the truck in the snow is a pain in the @#$.
So, any ideas as to why it won't go back and forth? I think the broken gear in the old one is why it didn't work. And I think the gear broke due to it only going one way, not back and forth like it should.
My AC quit working last time I went to the dealer, that is also when my radiator started leaking and the hose clamp on my power steering unit all of a sudden came loose.
And I don't think it was a coincidence. Not three things when I told them I was not going to authorize $1000.00 worth of work just to get my remote locks to work.

that is different, and in a different location.
The diagram you sent me first, shows the location next to where the two hoses connect into the dash.
The #101 in my car works, if I manually move the linkage for the motor that is messing with me.
