Out last night and the service 4wd light came on. The 4wd seems to be working. I was just getting ready to do a full tranny/transfercase, rear end service. I think I'll start with that but how do I get the light off in the dash......stealership? Any other thoughts as to what it might be. Its a 07 1500 5.7 auto with the elect. auto4wd transfercase. I was also wondering which case this is or where on the truck I find out?

 

I would start by downloading the service manual from the link in my signature and doing some searching and reading in it before going off to the dealer.
