Trunk light will not shut off toyota avalon

SOURCE: Trunk latch (electric) does not work on Avalon Touring

Your trunk master switch is probably off. Open the glove box, and, on the driver side of the glove box, the trunk master switch is located there. If this is activated, the remote and the dash switch are deactivated. Please repost if this does not solve your problem.

I would suggest to you to have the spiral cable (or 'clockspring') replaced. This is the electrical unit that transfers power to the air bag, the horn and the cruise control.

It is located right under the seering wheel.

Your description of the issue indicates to me that your spiral cable is loose, and making intermittant contact. If the vehicle had an air-bag deployment, this cable-device should have been changed.

There is a hidden deactivation button in the glove box. Just push it and your problem should be solved.

You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted

I had the same proble \m. You must of hit the button in the glove box. Just press the button in the glove box, and try it again.
