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

Read the full transcript
Symptoms of a bad tip-em and how to tell if your totally integrated power module is failing. If you drive a Chrysler Ram Jeep or Dodge, you're probably aware that these things are famous for causing absolute chaos when they go bad. So how do you know that your fuse box is actually your problem? The classic Chrysler symptom is a car that simply won't start because the internal fuel relay is cycling on and off, on and off and it ends up draining your battery overnight. You might also notice headlights that won't turn off, windshield wipers turning on all by themselves or power windows completely dying. After 30 years in OEM parts, I can tell you that these things punch way above their weight class as far as issues go. It's usually not a blown fuse, it's the internal circuit board layers and relays failing inside the box itself. So a visual check is usually not going to show you the damage. Dealer replacements are insanely expensive and known to be back ordered. Hit the link in my bio, check out my tested OEM fuse boxes and tip-em's or just comment your vehicle make and model and I'll hook you up with the correct replacement. [BLANK_AUDIO]
