hey i need some help really bad, i have a 2002 tacoma and for some reason i was driving down the highway and my 4wd indicator started like glowing, soft to bright, so i pulled over checked the harness and started it back up and ever since then my light wont come on when i put it in 4wd plus my front hubs wont lock so my front two tires dont spin, i cannot for the life of me figure out why.. anyone have a similar problem?
