Hi, I had recently purchased a second hand 2003 Jeep Liberty LTD edition 2.8 CRD automatic gearbox. Aside from the other things, I would like to ask a subject concerning the panel as per the attached: 1. The lights for the buttons are not working. I tried to change them, but no success. There is no power supply on the tracks. 2. Does anybody know what kind of lights are needed for the cluster panel? 3. Where can I find the electric circuit diagrams for the vehicles? Thank you in advance!
