So I have an S-10 (01), the daytime running lamps work, but once night comes, the lights dont work, only the brights, I was thinking maybe bulb replacements? Is there any type of sensor that would be involved??If so whats it called and where can I get one. I already checked all fuses in dash and on block, think it could be a relay or something. I really dont want to take it into a shop if I could fix it myself. Lil help please!
