Hi, I have a 2007 379 Peterbilt and the park light on the dash stays on. With that being said the door buzzer also isn't working. With the key on, park brake released, when you open door the buzzer should go off.
I've replaced door switch and the park brake sensor and still no improvement. Tried changing the dash ICU computer and that made no improvement.
Any advice would be great, Thank you
