Last week, I completely disassembled, cleaned, and repaired my original unit. Two wires had shorted out, the indicator light was burned out, and the unit had the beginnings of a bee hive inside. It's not very complicated. Nothing will spring apart when you take the cover off. However, if you disassemble the whole unit, there are two electrical contact plates inside which are separated by a spring. Mine did spring apart, but it was easy to figure out. My unit is back together, and all blinkers and flashers are working properly!
