Turn Off and remove the key...power stays on

Post by tonypatthou »

When I turn off the engine, and remove the key...the power stays on, the dash warning lights, etc. all stay on.
It happened last Sunday, apparently, the power stayed on all night, and my battery was totally dead. I had to replace it.
Why is the car doing that. Does that mean the ignition is bad, or is something else causing it .

Probably your combo relay is sticking.

Depending on the condition of the switch, that's a possibility.

Turns out the ignition switch was bad. We replaced it, and we also replaced the flasher relay too. Things are back to normal...for the moment.
