my wife’s 05 Tahoe started acting up by showing “service 4wd” on the way to church - then on the way to taking the kids to school this morning it showed “stability sys disabled.” I have read some other forms and they are all over the place on what to do or where to start. what they are saying is true — the car acts sluggish and seemed like it switched into 4wd.
looking for any help on where to start?? a sensor ?? some said the encoder motor?? even the 4wd on the dash being replaced??
any ideas would be appreciated & thank you
