We have a 2003 Toyota Tacoma. The instrument panel light is out. The owner's manual is no help and when I call the 800 nbr they tell me to pay $15 for a 2-day subscription so I can get the repair manual. (Because I don't want to go to dealership. Trying to fix the issue ourselves.) At night I am driving with a flashlight to see the speed and read the other indicators. Crazy huh?! Any suggestions as to the cause of the issue and how to resolve it? Thanks in advance!
