Flasher relay 03 XL Denali

[erock198]

I'm about to swap out the turn signal relay for the second time in a year in my 03 XL Denali. This one does not work when cold. I got it from Advance auto. My question is Is there a better one that will last longer?

Have you checked the lighting block by the rear wheel? Commonly corroded and mimics flasher issues intermittently

 

[erock198]

No I have not. I do know that after I changed it last time everything worked until just recently

 

[treehan77]

Swapping out the flasher "fixed" mine for a day until it stopped working again, cleaning up the light in block was the fix that kept it working after that

 

[erock198]

ok where is it? I know cars and trucks but not sure what you're talking about

Mine had one nasty corroded pin in he connector, cleaned it up and sprayed it with some cleaner, been fine for months now

ok the video says push the plugs then pull out. I"ll try one more time but I'm having trouble

ugh now one side of the block is hanging off. I think I need a lift. I think the terminals are indeed corroded

You're supposed to push the CLIP of the plug in them pull
