4 wheel drive wont work. Electrical or differenal?

Hello, Can you give me some details about the issue? Are you seeing warning lights on the instrument cluster? Are there any noises heard, vibrations felt, or change in performance? The AWD system on your vehicle is designed to transfer power when the drive wheels lose traction. So, if there is no need for AWD in a particular setting, you will have 2WD. It is not a full time all wheel drive system.
