My cluster has been dark for a long time, last time speedo was repaired I tried the soldering a jumper wire fix of the dimmer , still dark, all lights, console & shifter, Today I removed cluster & found my jumper wire repair had not held, so I soldered it again, better this time, & re installed, still no instrument cluster or console BUT, my shifter lights now, so I think my dimmer switch repair is working this time, I checked bulbs & their OK, any other known problems or suggestions?
