2007 chevy trailblazer_ls
Ok so the other day my service stabilitrak and traction control light came on. After i parked and turned the truck off and got back in later and restarted it the lights were gone. Then today i went 4 wheelin on a trail that i go on regularly and all lights were off and the 4x4 worked fine. About an hour after i went 4wheelin my service 4x4 light came on and now it wont engage 4 wheel drive. I have also been hitting alot of mud and water puddles lately. has anyone had this problem.
