1997-2001 Dodge Dakota Relay Guide: Diagnosing and Replacing
Solve common starting and electrical problems by understanding your Dakota's relays.
- Your Dakota has multiple identical relays; use the 'swap test' with a non-critical relay like the horn's to diagnose a bad fuel or starter relay for free.
- A 'crank, no start' issue often points to the fuel pump or ASD relay, while a 'no crank' issue points to the starter relay.
- Relay locations are shown on diagrams on the underside of the fuse box covers, both under the hood and in the cabin.
- Replacing a relay is a simple, tool-free DIY job that can be done in minutes.
Is a Bad Relay the Problem? Common Symptoms
Relay failures in the 1997-2001 Dodge Dakota often cause a few common, frustrating symptoms. Because different relays control different parts of your truck, the symptoms can point you to the specific relay that has failed.
- Engine Cranks but Won't Start: This is a classic sign of a bad fuel pump relay or Auto Shutdown (ASD) relay. The starter turns the engine over, but there's no fuel or spark to get it running. You may also notice you don't hear the brief, 2-second humming sound 🎬 Watch: How to test for fuel pressure and pump issues of the fuel pump from the gas tank when you first turn the key to the 'On' position.
- Engine Won't Crank at All: If you turn the key and hear nothing, or just a single click, the starter relay is a likely suspect. This relay is responsible for sending the high-power signal to the starter motor itself.
- Intermittent Stalling: A relay that is failing can work sporadically, causing the truck to stall unexpectedly while driving if the fuel pump or ASD relay cuts out.
- Component Not Working: If your horn, A/C compressor, or lights suddenly stop working, the corresponding relay could be the cause. Check your owner's manual or the diagram on the fuse box lid to find its location.
Choosing the Right Aftermarket Relay
For a part like a relay, you have several quality options that don't have to come from the dealer. Understanding the difference helps you choose the right part for your needs and budget.
OEM Mopar vs. Aftermarket
An original Mopar relay is what your truck was built with and offers a guaranteed fit and quality, but it comes at the highest price. For a simple and common part like a relay, a quality aftermarket part is often a perfectly reliable and more affordable choice. Many relays in your Dakota are standard ISO relays, meaning aftermarket versions are widely available and built to the same functional specifications.
Brand Tiers
- Premium Aftermarket (e.g., ACDelco): Brands like ACDelco are known for producing quality electrical components. While traditionally associated with GM, they make reliable parts for many vehicles, including Dodge. Choosing a premium aftermarket brand gives you a high-quality part with a good reputation, often for less than the OEM price.
- Standard Aftermarket (e.g., Replacement): This category includes various house brands and value-focused manufacturers. These relays are the most affordable option and are a good choice for budget-conscious repairs or for replacing relays on less critical systems (like the horn). They are designed to meet original specifications and function correctly.
Pro Tip: The Swap Test
Your Dakota's fuse box likely has several identical relays. If you suspect your fuel pump relay is bad, you can swap it with the identical relay for the horn. If the truck starts and the horn now doesn't work, you've confirmed the relay was the problem. This is a free and easy way to diagnose a bad relay.
Cost of Replacing a 1997-2001 Dodge Dakota Relay
Relay replacement is one of the most budget-friendly repairs you can perform. The part itself is inexpensive, and it's a simple DIY task.
| Part Type | Price Range | Notes |
|---|---|---|
| New OEM (Mopar) | $40 - $75 | Highest cost, dealer-guaranteed fit and quality. |
| New Aftermarket (Premium & Standard) | $17.03 - $36.94 | Excellent value. Includes quality brands like ACDelco and budget-friendly options. |
| Shop Labor | $50 - $100 | Most shops will charge a minimum diagnostic fee, as the replacement itself takes only minutes. |
Frequently Asked Questions
Where are the relays located on my Dakota?
Your Dakota has two main relay and fuse locations. The first is the Power Distribution Center (PDC) under the hood, which is a black box usually located next to the battery. The second is an interior fuse panel located under the dashboard on the driver's side.
🎬 Watch this quick guide to finding your fuse box locationsHow do I know which relay is bad?
First, identify the symptom (e.g., no crank vs. crank-no-start). Then, find the relay that controls that system using the diagram on the fuse box cover or in your owner's manual. The easiest way to test it is to swap the suspect relay with an identical one from a system you know works (like the horn or fog lamps). If the problem moves to the other system, the relay is bad.
Can I replace a relay myself?
Yes, absolutely. This is one of the easiest repairs you can do. It requires no tools. Simply locate the correct relay, pull the old one straight out, and push the new one firmly into its place.
What is the Auto Shutdown (ASD) Relay?
The ASD relay is critical in Chrysler vehicles of this era. It controls power to the ignition coil and the fuel pump's control circuit. A failure of the ASD relay will cause the engine to crank but not start, or to stall while driving. It is a very common part to fail 🎬 See how the ASD and fuel relays work together or be swapped for diagnosis.
