Turn Signal Issue
A recent problem has presented itself with my 04 Silvy. When I turn on my left turn signal, both signals flash. Does anybody know what the problem could be before I start tearing things apart? Yesterday it stopped after I turned my hazards on and then off but today that didn't work for me. Thanks in advance...

Mine was doing that for a bit, Did you just replace the bulbs? I was an idiot in a hurry at the parts store and grabbed the wrong bulbs...Not enough resistance I think? After I replaced them they started to blink at the same time, Got the right bulbs and it was fixed...Of course that was on a 1990 silverado, may not be the same for yours..Just a thought..Justin

I haven't changed the bulbs recently. I can't decide what it is. It's happened a couple more times and if I turn the right signal on and then go back to the left signal it will usually fix itself. Also sometimes it will blink both signals once or twice but fix itself when I turn the wheel the slightest bit making me think it may be some sort of short in the steering column. I also read that it can sometimes be caused by the trailer lights adapter. Anybody heard of this?

Greg (or anyone), what was the conclusion to this problem? I'm having the same issue with my '04 Silverado now. Thanks!!

Most likely the turn signal module. The replacements at Autozone and Advance are made by the original OE, most of the others are not...______________________
