The illumination bulbs in my car's dashboard (or instrument cluster) burned out and so I can't see what speed I am going at night. The service place charges way too much to fix it, so I want to fix it myself. Yesterday, I removed the dashboard from my car and replaced the 3 illumination bulbs. They did indeed appear to be burned out. However, when I put the dashboard back in, I still had no backlight on my dashboard. Do you guys have any ideas as to what other problems could be that would cause this issue?
