eill do ! thanks for your advise.Probably should have done that first, so far I wasted money for a used tccm and used button controls on the console with no luck.And also have a new actuator for the transfer case comming.Had the same problem two years ago and a junk yard tccm solved the problem then, man don't know whats up now. Hey globalhelper not sure how to post reply,wanted to let you know I had my car to local shop and they checked the actuator ,tccm, dash buttons, and said they were fine but could not find any fault codes. So $285.00 later still no fix.
