Trying to find problem with 99. With or without the key on the taillights stay on. Think it is somehow related to security system or remote start that was removed. Perhaps a wire that wasn’t removed??
Any ideas or things to check to narrow down problem?
Any help appreciated.
Thanks, Crutch

Will double check to see if brake lights and some little button/switch on pedal

Exactly which bulbs are staying lit? Could it be that the switch for the brake lights has gone bad and failed in the on position?

EDIT: HAH you beat me to it by 1 second!

Could be a short or a bad switch. Could be a radio wired incorrectly. You’d have to get out the wiring diagram and look to see where you have power that you shouldn’t. Then figure out why. It’s basically impossible to tell you with certainty without having the car present

Start with the easy most likely stuff and work from there.
1) Test the Switch (with so many years on the vehicle it wouldn't surprise me if the switch was malfunctioning). Start by pushing the plunger with your finger to see if it depresses and springs back to position. If it seems to function mechanically, move on to testing it for continuity when it's depressed and a break in continuity when it's released. This will require disconnecting the switch and using a testing meter. Keep in mind that the switch itself is only $3 - $6 on Rock Auto depending on the brand you get.
2) Check the wires by starting at the lights and follow the wires checking the areas of the body and chassis where the wires come through . It's a common spot for wires to chafe and short. Also check the bundle as it travels under the vehicle to make sure it hasn't been chewed etc.
