My 2003 Toyota Echo has two back lights in the instrument cluster. One of the lights would flicker if I hit a bump or something. I swapped the lights, meaning I put the bad light in the good light's place and vice versa, to help determine if it was an issue with the bulb or something else. The problem persisted with the bad light. So, I swapped them back because I preferred the other side to be more illuminated. After swapping them back, both lights went out and would not come back on. I checked the bulbs and both bulbs were burnt out. That's when I realized, when I swapped the lights back to their original locations, the car was still on. I'm worried I messed something up. So, I replaced both bulbs and they still didn't come back on. I checked the dimmer switch for continuity - that's good. I tried using a jumper between the two wires to force the lights to be always on - that did not work. I checked every 7.5, 10, and 15 amp fuse I have and they all look good. Everything else seems to work fine. I also checked the voltage going to the dimmer switch / rheostat. I tested it with a multimeter by touching the negative probe to the chassis and the positive to both probes on the dimmer switch and both wires going to the dimmer switch. I did not get any voltage reading on any of those. Any ideas? Did I mess the circuit board up when I put those lights back with the car on?
