on my o1 frontier the parking brake light is on constantly. When i release the brake it stays on. Ive tried to push on the sensor under the dash to see if its not being pushed in all the way in order to turn the light off and that still didn't work. What else could it be or what could i try. In utah, it will not pass safety inspection this way. Please help as my registration is past due and i need this truck for work.
