2003 Yukon SLT 5.3 4wd: I've had the 4wd selector issue for a while. Occasionally, especially in wet weather, the truck will be in 4Lo when I start it. Even though I never shift out of 2Hi. Two weeks ago a P0449 code showed up. I replaced the EVAP Solenoid, but it did not clear the code. Next the ABS light came on last week. The ABS sensors and wheel hubs are newer and are good. Finally driving home from work today I tried to turn the volume up with the steering wheel controls, but it turned the volume down. Next I tried the volume down on the steering wheel, and it tried to make a phone call. I'd love to put the truck in the shop and let someone figure this out, but you don't own a 20 year old vehicle with 330,000 miles if you can afford to pay someone to charge you hours of T/S time. Any help would be appreciated.
I do not have access to Tech2 Scan tool. I'm able to do most work myself, but I need a little direction here.
