What could the problem be if the dashboard lights do not illuminate?
Blown fuse, or they are turned off. Depending on the vehicle, you turn them up or down with either the trip meter reset button or the light switch. Try rotating either one. If fuses are not blown then it could be the bulbs are all blown too. All four of mine were blown. It's a bit of a process to get to them. Did mine the other night and took about 3 hours to get it done. I noticed a question posted on how to change these bulbs. It mentioned taking the entire dash panel out, but if only remove the dash shield you can pull the bulbs straight out instead of twisting out their sockets from the rear.
