Why does everything stay powered on with the ignition off now?

Asked by chris Sep 12, 2020 at 02:20 PM about the 2003 Toyota Tundra V8 SR5 4 Door Access Cab RWD

Question type: Maintenance & Repair

i need some help. I have an 03 toyota tundra with a 4.7 v8
the problem im having started the othwr day when i had a
coolant leak spraying all over under the hood. All of the
accessories stay on radio ac window controls etc... when
the truck is off and key is out of the ignition the gauge
cluster also stays poweres all the time as if the key was in
the one position. I have already replaced the ignition switch
thinking that was my problem but still have the issue. What
should i be looking for a short, bad ground?

I would suspect an electrical component or plug under the hood is still wet with coolant. Is there a junction box or fuse box under the hood, check that for wetness.

Yes i have the fuse box i havent checked it for any wetness yet i would.have thought by now it should be dried out ive let it sit for a 2-3 days.


Yup, the underhood fuse box is probably still wet. Hope that helps! Jim
