Dodge Dakota HVAC Blower Motor Resistor Guide (1987-2000)
If your Dakota's fan only works on high, this guide is for you.
- The most common symptom of failure is the fan only working on the highest speed setting.
- This is a very easy and inexpensive DIY repair, typically taking less than 30 minutes.
- Always inspect the wiring connector for melting or corrosion; replace it if damaged to prevent repeat failure.
- If the resistor fails repeatedly, the blower motor itself is likely drawing too much current and should be replaced.
Is Your Dodge Dakota's Fan Stuck on High?
A common issue for 1987-2000 Dodge Dakota owners is the climate control fan suddenly only working on its highest setting. This classic symptom almost always points to a failed HVAC blower motor resistor. This part is responsible for controlling the different fan speeds. When it burns out, the electrical circuit for the lower speeds is broken, but the high-speed setting—which bypasses the resistor—continues to work. Fortunately, this is a simple and inexpensive part to replace yourself.
Symptoms of a Failing Blower Motor Resistor
- Fan only works on high speed: This is the most common sign of a bad resistor.
- No fan at any speed: While less common, a completely failed resistor can prevent the blower motor from working at all.
- Inconsistent or erratic fan speeds: The fan may change speeds on its own or cut out intermittently.
- Burning smell from vents: A failing resistor can overheat and melt its plastic connector or wiring, creating a distinct burning smell. If you see or smell this, it's a fire hazard that needs immediate attention.
Check the Connector!
When the resistor fails, it often gets hot and melts the wiring harness connector. Always inspect the connector when you replace the resistor. If it looks burnt, melted, or corroded, you must replace it too. 🎬 See how to replace a melted harness and the resistor. Failing to replace a damaged connector will cause the new resistor to fail quickly.
Choosing the Right Aftermarket Resistor
For a simple part like this on an older truck, aftermarket brands offer excellent value. There's little difference in performance compared to the more expensive OEM part for this specific component. Brands like Dorman, Four Seasons (owned by Standard Motor Products), and Standard Ignition are all reliable choices. Many aftermarket kits from brands like Dorman even include a new harness connector, which is a great value if yours is damaged.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Part | $12.90 - $55.74 |
| New OEM (Mopar) Part | $50 - $80 |
| Shop Labor Cost | $50 - $100 |
Pro Tip: Consider the Blower Motor
If you have replaced the resistor before and it failed again, your blower motor might be the real problem. An old, worn-out blower motor can draw too much electricity, causing the new resistor to overheat and burn out prematurely. If it's a repeat failure, consider replacing the blower motor at the same time.
🎬 Watch this guide on troubleshooting both the motor and resistor.Frequently Asked Questions
Where is the blower motor resistor located on my 1987-2000 Dodge Dakota?
The resistor is located on the passenger side of the vehicle, under the dashboard, mounted in the HVAC housing near the blower motor itself. It is typically held in by two screws (often 5/16" or 8mm) and has an electrical connector plugged into it.
Is this a difficult repair to do myself?
No, this is one of the easiest repairs you can do. It requires basic hand tools and usually takes less than 30 minutes. You will need to work in the passenger footwell, which can be a bit cramped, but the process is straightforward: unplug the connector, unscrew the old resistor, screw the new one in, and plug it back in.
🎬 Watch this step-by-step walkthrough of the resistor replacement process.Why did my new resistor come with a new wiring pigtail?
Many aftermarket kits include a new connector because the original often melts from the heat of the failing resistor. If your original connector shows any signs of melting, burning, or corrosion, you must cut it off and splice the new one onto your vehicle's wiring to ensure a good connection and prevent the new resistor from failing.
Are there any recalls for the blower motor resistor on my Dakota?
Yes, there was a recall (NHTSA Campaign ID 91V004000) for early models concerning the resistor overheating due to water intrusion from the cowl area, which could cause a fire. Another recall (03V078000) mentioned the blower fan stopping, which could affect windshield clearing. While these recalls are old, it highlights that this has been a known issue area for the vehicle. You can check with a dealership to see if your specific VIN was affected and if the recall work was performed.
