From the shop
Body and accessory circuits on these run through this fuse block — fuses and relays together, standalone on this generation rather than folded into a switched module. When one of those circuits goes dead or starts acting up intermittently, this panel is usually where the problem traces back to, though it's rarely just one component failing outright. Tested functional. All relays and fuses checked. Cleaned. Part number: 56004729. Fits 1988–1989 Dodge D150, D250, D350, W150, W250 and W350. Worth checking the numbers on your old panel against the one above before ordering, just to be sure. Ships same day Mon–Fri before 3pm EST. — Hubes
