2004 Tahoe - left turn signal rapid blnking & stopping.

[Icarus]

Hey guy's, I have a 2004 Tahoe that is driving me nuts. The left turn signal blinks rapidly then stops or just doesn't work at all. I've replaced bulbs, the pigtail at the front, fuses are good relay is good as well as changed the indicator switch in the column. Please help any advise would be appreciated, thank you.

how’s the hazard switch? Does it do it when they’re on? You can try jiggling the switch to see if it’s the cause. These also had a problem with the flasher module but my guess is the hazard switch.

Welcome to your first post at the forum.

Look at the right rear area, up at the inner fender area for this: https://www.rockauto.com/en/moreinfo.php?pk=1533778&cc=1424247&pt=4132&jsn=1567

That's a good testing location.

Front or back, or both acting up?

Has the flasher been changed?

Confirm that the trailer lighting connector is clean inside the flip cap. If you pull the trailer turn signal fuses, does it still act up?

Pics of the truck, please.

You are already receiving sage advice from the knowledgeable folks on this Forum.

As I understand it, your truck has a specific flasher/hazard module, 12 pins. Have you checked it out, and possibly replaced it?

Hi, thanks for the advice and when the hazards are on the left side blinks rapidly outside but nothing on the dashboard., so I think I'll replace the hazard relay switch next.
