Ive got an older volvo wca64t truck and i cant seem to get the read out. Ive tried button in, key on, release button, but get nothing. I know the button is working because i can hold it for 3-4 seconds and it will shut the cel light off, but it comes back on right away. Am i doing something wrong or what can i do to figure the button out?
