Are your RAM 1500 power folding mirrors suddenly refusing to fold? This frustrating problem affects many owners, but the good news is that the solution might be simpler (and cheaper) than you think. Whether you have a newer 5th generation truck with stubborn mirrors or an older 4th generation model with electrical issues, this guide will walk you through every diagnosis and repair option.
Why Your RAM 1500 Power Folding Mirrors Stopped Working
Before diving into complex repairs, it’s important to understand that RAM 1500 mirror failures generally fall into two categories:
For 5th generation trucks (2019-present), the problem is usually mechanical – specifically a failure-prone plastic gear inside the mirror.
For 4th generation trucks (2009-2018), the issue is typically electrical – often related to a blown fuse or wiring problem.
Let’s start with the simplest fixes that might save you hundreds of dollars.
Quick Reset Procedure: Try This First
RAM has an official reset procedure that often fixes folding mirror problems, especially if they’ve been manually folded or pushed:
- Make sure your truck is in “Accessory” or “Run” mode (press the start button once or twice without pressing the brake)
- Press the power-fold button to fold the mirrors closed
- Press the button again to extend the mirrors
- Repeat this fold/unfold cycle three times
During this process, you might hear a click or snap – that’s normal! It indicates the internal clutch mechanism is resetting. This simple procedure fixes many mirror issues without any parts or tools.
Diagnostic Checks to Pinpoint the Problem
If the reset procedure didn’t work, let’s figure out exactly what’s wrong:
Listen for Motor Sounds
Press the fold button and listen carefully at each mirror:
- Motor whirring but no movement: This indicates a mechanical problem (likely the plastic gear in 5th gen models)
- Complete silence: Points to an electrical issue (fuse, switch, or wiring)
- Clicking or grinding: Suggests mechanical issues where gears are slipping or stripped
Check the Specific Symptoms
- Do both mirrors fail, or just one?
- Do other mirror functions (adjustment, heating) still work?
- When did the problem start? (After car wash, impact, etc.)
5th Generation RAM 1500 (2019-Present): Fixing the Mechanical Issue
The overwhelming majority of power folding mirror failures in newer RAMs are caused by one faulty part: a brittle plastic gear inside the mirror assembly.
The Plastic Gear Problem
This small plastic gear transfers power from the motor to the folding mechanism. Over time, the stress of folding these large mirrors causes the plastic teeth to strip or the gear to crack completely. When this happens, you’ll typically hear the motor running, but the mirror won’t move.
Repair Options for 5th Gen RAM Mirrors
You have three main options:
1. DIY Metal Gear Replacement ($66)
The most cost-effective permanent fix is replacing the plastic gear with an aftermarket metal one. Companies like GruvenParts make brass replacement gears that won’t fail like the originals.
This repair requires:
- Metal gear kit (~$66)
- Basic tools and a rotary tool
- 2-3 hours of careful work
While this repair is more technical (involving opening the sealed mirror housing), it addresses the root cause permanently for a fraction of dealer costs.
2. Full Mirror Replacement (DIY: $150-450, Dealer: $1,400+)
If you prefer not to open the mirror housing, you can replace the entire assembly. Dealerships charge $1,400+ per side, while aftermarket mirrors cost $150-450. However, new OEM mirrors contain the same failure-prone plastic gear.
3. Body Control Module Reset
For erratic electronic behavior (not mechanical failure), try resetting the Body Control Module:
- Disconnect the negative battery terminal, then the positive
- Touch the disconnected cables together (away from battery posts) for 30-60 seconds
- Wait 15-30 minutes
- Reconnect the positive terminal first, then the negative
4th Generation RAM 1500 (2009-2018): Fixing Electrical Issues
Power folding mirror problems in older RAMs are typically electrical rather than mechanical.
Check the IOD Fuse First
The most common failure point is the Ignition Off Draw (IOD) fuse in the engine bay Power Distribution Center. This fuse powers multiple systems including the mirrors, radio memory, and dome lights.
If your mirrors, radio presets, and interior lights all stopped working simultaneously, you likely have a blown IOD fuse.
The Wiring Harness Problem
If your IOD fuse is blown, check the mirror wiring harness where it passes between the mirror base and door frame. The common scenario is:
- The harness gets pinched during mirror installation
- Insulation wears away over time
- Wires short against the metal door
- The short blows the IOD fuse
Fix this by:
- Replacing the blown IOD fuse
- Carefully inspecting the mirror wiring harness
- Repairing any damaged wires and properly routing the harness
Other Electrical Checks
If the fuse is good, check:
- The power mirror switch on the driver’s door
- The Driver Door Module (DDM) and Passenger Door Module (PDM)
- For power at the mirror connector using a multimeter
Checking Fuses: Locations and Access
For proper fuse checks, you’ll need to access the correct fuse box:
4th Generation (2009-2018): The Power Distribution Center is in the engine compartment on the driver’s side. Look for the IOD fuse.
5th Generation (2019-Present): The fuse box is in the driver’s side footwell behind a trim panel. You’ll need a 7mm socket to remove two screws. Check fuses F20, F24, and F66 which power the mirror functions.
Don’t Confuse Mirror Issues with the Glass Recall
There is a safety recall (NHTSA 24V-754) for some 2020-2023 RAM 1500 Classic trucks with heated trailer-tow mirrors. This recall addresses mirror glass that may detach from the backing plate.
This recall is completely unrelated to power folding functionality problems. The recall only replaces the mirror glass, not the folding mechanism or motor.
Enabling Auto-Fold Features
Many higher-end RAM 1500s have the hardware for automatic folding mirrors (when locking/unlocking) but this feature is often disabled from the factory.
While the owner’s manual mentions an “Automatic Power Folding Mirrors” setting in the Uconnect system, many owners find this option missing. You can enable this feature using aftermarket OBD2 programmers like AlfaOBD or Tazer DT, which allow you to access and modify hidden vehicle settings.
Cost Comparison of Repair Options
| Repair Option | Parts Cost | Labor Cost | Total Cost | Notes |
|---|---|---|---|---|
| Dealership Full Mirror Replacement | ~$1,326 per side | $100-$200 | $1,400-$1,500+ | Uses same failure-prone plastic gear |
| Independent Shop Mirror Replacement | $200-$700 | $100-$200 | $300-$900 | Quality varies by shop |
| DIY Full Mirror Replacement | $150-$450 | $0 | $150-$450 | Requires basic tools |
| DIY Metal Gear Replacement (5th Gen) | $66 | $0 | $66 | Most cost-effective permanent fix |
| DIY Fuse/Wiring Fix (4th Gen) | <$5 | $0 | <$5 | If issue is just a blown fuse |
Choosing the Right Repair Path
For 5th Generation owners, the metal gear replacement is highly recommended. While it requires more technical skill, it’s the only solution that both fixes the problem permanently and does so at minimal cost.
For 4th Generation owners, start with electrical diagnostics. Check the IOD fuse and wiring harness before considering more expensive component replacements.
With careful diagnosis and the right approach, you can get your RAM 1500 power folding mirrors working again without breaking the bank. The satisfaction of fixing this common problem yourself – and potentially saving over $1,300 – makes the effort well worth it.
