Turn signal stays on after Explorer is shut off

[Franknfike1]

When I turn off my 05 Explorer XLT with the turn signal on, the turn signal lights outside the car stay on in a constant state (not blinking). It does this for both the right and left side. Has this ever happened to anybody?

No, because I don't leave my turn signal going and then turn the engine off.

Good one - thanks for the help....

Do you have a European version? Sounds like a single sided parking light function like my Benz has, but it's on a separate switch and turns on the low intensity parking filament not the bright turn signal one.

Do you have a aftermarket alarm system? Or a aftermarket light flasher (ex police explorer) or anything?

I'll pull up the wiring diagrams for you, so I get the correct ones do you have auto headlamps or manual?

Thanks TechGuru. It's not a European version so I think that rules that out. No aftermarket alarm system or light flasher.
Thanks for pulling the wiring diagrams - it has manual headlamps.

Looking at that I think you may have a bad flasher relay as it looks like it is responsible for separating the always hot line for the hazards from the hot in run line used for turns.

Part number SF633.

Thank you! I'll install it and let you know if it resolves it for me.

That seems to have taken care of the issue - thank you TechGuru!

Yep. I believe the diode in your old one died.
