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

What was changed before this issue came up?

You may want to completely disconnect the front and rear light housings and test. At a minimum, remove both left side bulbs.

' the left turn filament is very dim and the read does not do anything.'

The left side might have a near short which would allow just a little voltage to the bulb. Is the front dim and the rear out completely? The short may be in the rear housing wiring. Again it might be prudent to remove all wires from the rear and see if the fuse blows.

A guy brought his 911 to me where he had to put a 25A fuse in the left side turnsignal to keep it from blowing. The front turnsignal was dim and the rear was out. The fuse was getting hot. We disconnected the rear wire at the fuse panel and the front turnsignal got bright as expected and the fuse was cool. There was some short in the rear housing.
