Push button 4wd not engaging

Anyone have any insight? I push my button, sounds like it’s struggling but goes into 4wd.drove all morning just fine. I took it out of 4wd and now it doesn’t want to go back to 4x4. I’ve tried just about everything. Took the actuator black cap off and cleaned all contacts and put dielectric grease in there. Worked for a day, not working anymore. It’s also only -15 here right now.

 

Is this in the 3.4?

 

Yes 3.4 and today it seems to work. Any chance these are known for freezing in cold weather?

 

I've had it not work for me in the snow before. Try it when it's warmer and use it more often.

 

Okay thanks guys

 

Time for j shift tcase and manual locking hub. Guarantee to work every time

 

Been thinking about it, just not sure how to. Does the j shift bolt directly onto the auto tranny? Just need to cut a hole in the floor for the j shifter?
