Got ya! Check thefuse and make sure none are blown. Its a pain to pull the dash and replace the lights in most cars some trucks are easy but not sure about yours. Bulbs a a buck or two usally.
Maybe autozone or another parts store can code scan it for you. They usally have code scanners with display screens. Its also easy to test the egr valve. I think its 12 v it flows air no volts its closed. If you have a vacum pump for brakes you can use it to test the valve and the egr. Egr should open on vacum and hold air if it leaks down its broken and needs replaced. Other than that its carbon build up.
