was working on the truck yesterday and a bulb blew, replaced and still didnt work, checked the fuse it was blown as well so replaced that. then got back in to go to bdubs and i had no speedo, the abs light is on and my e-brake light is on. its throwing two codes, one says lost communication with speed sensor, the other says lost communication with abs module. thinking its the fuse 13 but ive been to autozone, oreillys, and walmart and not one of them had a 25 amp fuse! not sure if its the fuse because it doesnt look blown. if its not then its the rear axle speed sensor which is only $20 and an easy swap. also i ordered 16 E3 spark plugs with my heddman headers im switching out next month. are they ok to use?
