Plymouth Duster Power Window Relays

Plymouth Duster Power window relays

Starting at low prices, AutoBuffy stocks multiple power window relays from top OE-quality brands to fit the Plymouth Duster. The power window relay is a small electrical switch that routes current from the fuse box to the window motor circuit. When it fails, one or all windows stop responding — a safety and convenience issue worth fixing promptly.

Signs your Plymouth Duster needs a new power window relay

  • One or more power windows are completely unresponsive when the switch is pressed, with no motor noise at all
  • All windows stop working simultaneously while individual door switches and the master switch both fail to respond
  • Windows operate only intermittently, working normally then going dead without any pattern or warning
  • You hear a faint click from the fuse box area when pressing a window switch but the window does not move
  • The affected windows work when jumped directly at the relay socket but not through normal switch operation
  • A burnt plastic or electrical smell near the fuse box coincides with window failure, indicating a relay that has overheated or shorted

Which power window relay should you buy for your Plymouth Duster?

Power window relays vary by amperage rating, relay configuration, and whether they control a single window or the entire window circuit. Matching the correct relay type and terminal layout to your Plymouth Duster's fuse box is the most important buying decision — an incorrect amperage rating can cause premature failure or blown fuses. OEM-equivalent relays are generally the safest choice, but heavy-duty upgrades are worth considering on high-mileage vehicles.

OEM-Equivalent Relay
Best for
Straightforward like-for-like replacement on a well-maintained Plymouth Duster
What you get
Exact terminal layout, correct amperage rating, and plug-and-play fit with no wiring modifications
Heavy-Duty Relay
Best for
High-mileage Plymouth Duster or one that has burned through relays more than once
What you get
Higher-rated contacts that resist heat and arcing better than standard relays under repeated cycling
Integrated Relay Module
Best for
Plymouth Duster applications where the relay is built into a multi-function body control or window control module
What you get
Single-unit replacement that handles multiple window circuits, reducing the risk of mismatched components
Universal Relay with Harness Adapter
Best for
Situations where an exact OEM part is discontinued or backordered for your Plymouth Duster
What you get
Flexible terminal configuration with an included adapter pigtail; requires careful amperage and coil-voltage matching

Replacing the power window relay on a Plymouth Duster

Easy⏱ 15–30 minutesFuse puller or needle-nose pliersFlathead screwdriver (for fuse box cover clips)Digital multimeter (for verification)Owner's manual or fuse box diagram

Locate the correct relay slot using the fuse box diagram, then pull the old relay straight out of its socket — no tools are needed for most plug-in relay types. Press the new relay firmly into the socket until it seats fully, reinstall the fuse box cover, and test all window switches before closing up. If windows still do not operate after relay replacement, check the window motor and switch with a multimeter before assuming the new relay is defective.

Frequently asked questions

How much does it cost to replace power window relays on a Plymouth Duster?
Parts start at low prices on AutoBuffy for the Plymouth Duster. The relay itself is an inexpensive component. DIY replacement takes under 30 minutes in most cases and requires no special tools. Shop labor, if you choose a professional, is typically billed at under one hour, making this one of the more affordable electrical fixes.
Can a bad power window relay drain the battery on a Plymouth Duster?
Yes, a relay that is stuck in the closed position continuously energizes the window motor circuit even when the ignition is off. This creates a parasitic draw that can drain the Plymouth Duster's battery overnight. If you notice repeated dead batteries alongside window problems, test the relay before assuming the battery or alternator is at fault.
How do I know if it's the relay or the window switch causing the problem on my Plymouth Duster?
Swap the suspect relay with an identical relay from another circuit in the fuse box — many vehicles use the same relay type in multiple slots. If the window works after the swap, the original relay is faulty. If the problem follows the switch position rather than the relay, the switch or wiring is the more likely culprit.
Where is the power window relay located on the Plymouth Duster?
On most Plymouth Duster applications the power window relay sits inside the main underhood fuse and relay box or the interior fuse panel near the driver's knee area. The exact slot is identified by a diagram printed on the fuse box cover or in the owner's manual. Some vehicles integrate the relay into a body control module instead of a standalone socket.
How long does a power window relay last on a Plymouth Duster?
Power window relays are rated for tens of thousands of switching cycles and typically last the life of the vehicle under normal use. Premature failure is usually caused by voltage spikes, a binding or overloaded window motor that draws excessive current, or moisture intrusion into the fuse box. Fixing an underlying motor problem protects the new relay.
Will a power window relay from a different brand work on my Plymouth Duster?
Yes, provided the replacement matches the original in coil voltage, contact amperage rating, terminal count, and physical footprint. Brand matters less than specification accuracy for relays. AutoBuffy lists multiple options for the Plymouth Duster from top OE-quality brands, all verified to match OEM specifications for a correct fit.
