Headlight problems with 2001 gmc t7500. When lights are off the dash is showing that there on and when I turn them on I only have one light and dash light goes out. But using beams there all on. I am having trouble finding wiring diagram. Any help would be great. I am hoping for link to find wiring diagram or any info if available. Thank you.
