all of the 4wd drive lights come on and stay on while driving, and 4wd is inoperable. when this happens the shift from 1st gear to 2nd is rough untill it gets to 1500 rpms. I replaced the switch to no availe. no mechanic can figure it out. I dont want to take it to a dealer. they wanted to charge me 350$ to install the switch (50$ part) (took me less than a minute to install). what is the problem? please help.
