i was looking under the truck a noticed a wire unpluged from the tcase pluged it in and nothing still

 

Have you pulled the connections at the TCCM (located behind the passenger side kick panel) and inspected them for corrosion and/or bent pins? Tested the resistance from the switch?

Check out the NV236 threads in the Tech Article (DIY) Index link found in my signature below.

 

i pulled the tccm and two pins on one side have some corrosion i tried to clean the pins on the box with some fine sand paper but the plug i cant get into put it back in and nothing all 4 lights still on and doesnt make any noise or do anything when bottuns pushed in

 

i was reading and most post talk about vacum lines going to the tc all i have is some wires and plugs down there i dont se any vacume lines or places for them to plug into
