Four wheel drive not working properly

Do you have an all wheel drive or 4WD vehicle?

Do you have a 2WD button or not? That will tell us which you have.

This does sound like there is an issue but we need to find out if all wheels are spinning when you put it in 4WD. This means we need to start with putting it in 4WD and looking under the vehicle to see if the front drive shaft is spinning when you move the vehicle forward.

Then we need to lift the vehicle and put it in 4WD and see if all tires spin. You may need to rev the engine to get them all spinning as when there is no load on the drive train they don't all spin but this doesn't mean there is an issue.

This could be normal if the snow was deep enough but let's run through this and see what turns up. Thanks
