4x4 selector problems

I have 02 LS 4x4. Sometimes, mostly when its colder, I switch from 2wd to 4hi. 4low and the 4x4 light comes on. All the lights on the selection swich go off. I turn it off and back on the lights come on, I then all shut back off with 4x4 light still on. 4x4 is engaged at this point.

Sometimes it will finely start working and switch to 4low and will work correctly. Any help?
