GMC Jimmy 4WD Problems
1.If you press 4 Hi from 2 Hi.....the 2 Hi light goes out and 4 Hi light blinks but does not stop blinking although 4WD is engaged(I can feel it while turning).
2.When selecting the Auto 4WD button the Auto light starts blinking and instead of being in the 4WD "on demand" mode it goes directly into 4WD.
3.No code or check 4WD lights appear on the dash.
The repair facility had closed for the day when I discovered all of this and I plan on going back but I just wanted some ideas as to the problem before I do. Thanks for any help.
