Hazards turn on when i signal a left run.....

[ohfourtahoe]

On my 04 Tahoe, when I signal left, the hazards turn on. It does not happen when i signal right.

Has anyone else had this problem?

Thanks

Mine did it with either like a week ago. First check the connections in the "rear lighting junction block". That's where my problem was, one pin was heavily corroded. This junction block is located near the rear wheel, just look up under there next to the exhaust where it sticks out by the wheel. I cleaned mine and no problems yet, but a new one is only $15 in Amazon. If that's NOT it, it's probably the flasher. This costs more like 50 bucks. Read the troubleshooting tree in my thread, it hadn't been posted yet when I decided to gamble on the flasher and lost.
My truck also had the turn signals in the instrument panel lighting up when I pushed the brake pedal. First plug I took of the junction block was the blue supply one and one pin was NASTY, cleaned it up, straightened it and good since.

Any other input on this? My 03 Yukon has the same problem as "ohfourtahoe". Right turn signal works fine, but when I use the left, they all flash like the flashers are on.

Click on and off, and otherwise flick around your hazard switch a bit

Did you check the rear lighting junction block? Easy fix or replace

Bad bulb somewhere will do that

I first checked the rear junction block. Unplugged and cleaned everything (it all looked pretty clean already). That did not fix it. Put in a new Delco flasher and that was it. I work for a Delco distributor so cost was only $50 but I'm glad it fixed it. This was a helpful video for me.
