I was wondering if anyone can help me with a small problem of my Pacifica 2007 4x4 4.0 Litre engine.

Recently some of lights of my panel stop working in particular the button of speed of the heating fan is not working and as well rear seats heating button. I was wondering if there is a possibility to fix it somehow by myself as taking it to dealer would cost a lot for such a small problem. Perhaps someone knows how can I detach the plastic decore panel and simply change the light bulb???? Same with the rear seat heating button.

Thank you in advance for any advice !!!
