Dangerous cause of both headlights not work at the same time (Suzuki Every LE-DA62V)

This is Suzuki Every that I kept in that the headlight suddenly went out during the night running.

MY2001 LE-DA62V K6A 3AT Mileage 159,000km

The high beam is lit, and the running view seems to have been maintained, but I think that it was surprised when the front of the eyes suddenly became pitch black.

As a cause of the left and right headlights not turning on both, there is a pattern that it runs without noticing the filament disconnection of one headlight valve, and notices only after the other headlight valve is cut.

However, in this case, both headlight valves are normal, and there is no break of the fuse.

Because it is a relayless electrical circuit that intermittents a large current, the malfunction near the dimer switch at hand is thick.

After removing the steering wheel and airbag equipment, there is a dimmer switch ASSY that handles the operation of headlights and wipers.

The first thing that caught my eye when I removed it was that one of the connector pins was burnt by overheating.

It may be a flame retardant material, but it is associated with a vehicle fire.The increase in resistance value due to poor contact leads to local overheating, but protection with fuse is invalid because it is not an overcurrent.

You can't find used parts that fit exactly in a manufacturing vehicle just before and after the big miner.Because it was said that the car inspection expiration and the transfer were under consideration in a little already, the purchase of expensive new parts was refrained, and it kept it to the first aid.

The dimer switch is further disassembled, and the fallof point of the contact enclosed in a red circle is filled with solder.

The burnt contact pin connected the matchfrom the stock part, leading to temporary recovery of the low beam lighting.
