$ wheel drive concern and side mirror problem

[IMtnBike]

I just purchased a 2002 Envoy 4x4. I am not sure if the 4 wheel drive is engaging. How do I know if it is without having someone check it in the snow. On my 96 Jimmy, there was a light associated with the button pushed to engage. Also, I could feel when it was in 4 wheel drive. I do not feel any difference when the Envoy is in 4x4 or AWD.

Also, my passenger side mirror glass won't stay set . After I leave it overnight it goes out of adjustment. The driver's side works fine.

Any help would be deeply appreciated.

Does the selector light on the dash show you are in 4wd?

It does not show anywhere on the dash or on the switch.

Ok, this is a common issue, I replaced that dash switch on my 2002 2x over 150k miles. Cheap enough do that see what happens, next step gets more expensive.
