I am getting a "SERVICE 4WD" message on my display. I have had this problem twice int he past; both times the repair was $600.00 +. What happens is I am unable to go into 4wd or any of the variants available, or the vehicle will stay in what ever mode I was in at the time. I have a 2004 Yukon XL 1500 with the push button selection for choosing my traction. Both times in the past when the same problem happened a servo was replaced. I did not think to ask for the old one, or even for a part number in case it happened again.
Well here I am... again.
Does anyone know what I am talking about, what the servo part number is, or how difficult this repair is to do myself? Is this a common problem, if so is there an upgrade I can get? Or if this is not a common problem, is there a reason my vehicle will need the same servo replaced three times, how do I prevent it from happening again?
Thanks in advance.
