left turn signal problems, feel like i have tried everything Options

[jeff dodge]

I am having trouble with my left turn signal. Let me detail; ground tested and is good, replaced , replaced column switch, new relays, new bulbs, swapped housings from left to right, new fuses. noticed that when I clicked the emergency flashers it blew that fuse. Right works fine, the left turn filament is very dim and the read does not do anything. I have spent two weeks trying to track this down. I have built entire harnesses for vintage race cars and this has me baffled. Please help! Thanks, Jeff

You might want to check all the bulbs and fixture. Front and rear. Pull the bulbs out and throughly clean the receptacle. Blow them out with compressed air. I had a little piece of rust get loose in there and fried a brake light switch. I figured it out after I installed a new one and could feel the switch getting hot. Sure enough that was the issue. You could have the same thing with a turn signal fixture. Simple to fix but drove me crazy for a while.

I will try and list the details of my findings;
1)all of the L/R light housings were tested with every bulb socket connected with jumper leads directly to the battery and every bulb socket functions properly.
2)when all 4 light housings connected the L/front turn comes on, but is very dim. The L /rear turn does not have power at the housing even though it checked out with a direct battery connection. Every other L/R light functions as it should.
3)all ground connections check out.
4)I have replaced every bulb, tried 2 new proper flasher relays, installed brand new column turn signal switch, installed brand new emergency flasher switch, I installed all new fuses.
5)I double and triple checked every wire connection and all are in the proper location.
6)keep in mind that the R/side turn signals work fine.
7)with all of these steps and new parts, it's the same results before I started to unravel this problem over 3 weeks ago!
Any thoughts with this information would be greatly appreciated. Jeff
