Light issues

Last week, two light problems started. One: the inside trunk light remains on when the car is operating.

Two: When I touch the brake, a dashboard light comes on which says a door is open.

Any ideas where I can try to diagnose this?


!) Trunk light on.

Spray the light plunger switch with electrical contact cleaner and work it by hand a few times before closing the lid.

If the switch is in the latch, spray it.

  1. Door ajar light.

Again, spray all the door switches (plungers or latches). Ensure the switches engage with the doors (and trunk lid).
