Up for sale is a good functional Suzuki Esteem Dash dimmer switch. This is the unit that dims the gauge cluster lights, located to the left of the gauge cluster. These are reasonable easy to exchange. Pop it out, and plug in the new one.  Take a look at the picture to be sure if this is right for your car.  Good used unit from a recent crash damaged car - comes with a 30 day warranty.  I have tested this unit for correct resistance with an ohm meter and it works properly through it's working range. It will come to you as seen.  Do NONE of your dash lights not work, or do they flicker when you try to adjust the brightness, or only work on full bright, or only occasionaly when you fiddle with the dimmer switch?  All of these are signs of a possibly defective dimmer switch. These are starting to be hard to find in good working condition, $122 list from GM, 1/4 that here. Bargain alert!!! Keep your classic Suzuki going.
