My drivers side front turn signal bulb keeps burning out. When I replace the bulb I notice on the bad bulb that one of the contacts and the plastic around it is burnt/slightly melted. I am going through bulbs at a rate of one every two days. Same problem each time. Fuse looks okay and is the right # of amps. Could it be the socket or flahser relay?

SOURCE: burnt plastic smell that burns your nose

sounds like it could be electrical then... have you done any changes to the electrical at all? rewiring, changing headlights, etc? I had a similar smell when I changed my headlights... new headlights were defective and were melting the housing and harness...

Replace the light socket. you can get them at your auto parts store. Get some heat shrink tube at the same time. It seals better than tape on the joints. Hope this helps.

Hi.

the drive belt tensioner melted the plastic parts in it. The faulty drive belt must be replaced, and the remaining drive belts must be checked. According to factory and to safety standards, the drive belts must be checked every six months. Often the dive belts fitted in the vehicle with drive get checked only when doing the periodic revision. In your case an object stuck in the drive belt tensioner, or the tensioner itself caused the problem. Even if the tensioner is working, for safety reasons it must be replaced.

Here a service manual. Check page 15 in pdf.

Regards.

SOURCE: Left turn signals won't flash, Right side works fine. Replaced front and rear turn bulbs (rear was burned out). Bulbs come on fine on the left side, they just won't flash.

Gday mate, we had a problem with another late model vehicle similar to that, the bulb that was put into the reverse light was not exact brand product ( ohmage was slightly wrong ) and fowled up computer, correct bulb in place and disconnect battery to reset K A M ( keep alive memory) problem solved, BEWARE, some vehicles cannot have KAM reset except for dealer computer tethered reboot , just try putting the factory correct bulb(s) in and see how it goes, geoff. hope this helped.
