Technical Fiat Panda 169 Right Headlight burnt H4 Connector?

[kavil]

Good evening everyone.

Yesterday coming from work, we noticed that our right headlight was not working. Today i opened up the hood to change the H4 bulb thinking it burnout but i noticed the connector is burnt. I nevertheless changed the bulb but replacement did not worked. I connected old and new ones to the Left connector and both of them worked.

So connector was suspicious. I measured the voltage on the pins and other 2 pins were spot on with the left working connector however burnt should show 0.35v instead it showed 0.05v. No burnt fuses.

I searched the internet a little and found a connector near the ODB II port. and the pin is burnt there as well. I cleaned each male- female pin and H4 connector with contact cleaner and both of them is working as expected.

My question is, i think my cleaning and reseating connectors solved it for a moment but it wont be permanent, I do not know what this connector called so i could not search this issue further.

Can i just buy new H4 connector and this other multi pin connector and replace it and hope for the best or is there a better solution for such thing?
Thank you

If all else fails you may be able to buy packs of the male and female connectors and change just the individual connectors in the block once you release the "tang" that hold them in.
Alternatively solder a wire from the dodgy connection from both sides to a fuse holder so you can unscrew before unplugging original connector if required, so bypassing the burnt/damaged area.
You can replace the lucar type connector at the bulb individually also then solder to make a good connection.
If slight resistance at connection caused by loose/weak plug resistance and heat soon builds up, so not uncommon.

Well known an documented fault

I'm afraid that keeping the printed leads on the internal circuit board will cause the problem to recur over time.

So I noticed that one of the dipped beams on our Panda wasn't working. Changing the bulb didn't fix it and I noticed that the connector was a bit melted and charred. I checked the other one and although it was working it was so much worse that it fell apart as I took it out. So I did a bit of...

the old days we simply fitted relays. Today, that would mess up the CanBus. It might be possible to fit a ballast resistor to the relay switch coil. But you’d be on your own making it work.
