Turn Signal Bulbs keep blowing

[ironhar]

I've got a '97 TA. The left turn signal bulb keeps going out. Every time I replace it, it goes out again in a couple of days. The connector was burnt and warped, so I replaced it, but the bulb still blew. The right side connector is burnt as well, but that bulb doesn' t blow. I'm using the correct bulb, 3057, and it's only the left side that goes out. I also replaced the turn signal housing, thought condensation was causing the bulbs to blow, but that wasn't it either. Anyone have any ideas what the next step would be? Any help is much appreciated.

The 3057 bulb has two filaments. Are you sure the right one is working as the signal? It should be the longer one I think. Compare it to the other side.

Also check the action of the side marker lamps as the signals flash. I think they alternate too depending on if the parking lamps/headlamps are on. You may have a wire crossed on that side, or a bad ground.
