Ram 1500 Power Folding Mirror Popping Noise – Common Problem and Fix
If you’ve ever walked up to your truck, hit the mirror fold button, and heard a loud popping or clicking noise that just doesn’t sound right—you’re not alone.
This is a real-world case involving a 2019 Ram 1500 Crew Cab where the power folding mirrors were acting up. At first glance, it seemed like a calibration issue. But as we dug deeper, it turned into a textbook example of why proper automotive troubleshooting matters.
If you're into diagnosing car problems or just want to avoid throwing parts at a vehicle, this is one you’ll want to understand.
🔧 Recommended Diagnostic Tools
When you're diagnosing modern vehicles, having the right tools makes all the difference. A basic code reader will only get you so far—you need tools that let you see what’s really going on and test components properly.

Vehicle Overview
This case involves a 2019 Ram 1500 Crew Cab, part of the newer DT platform. These trucks are loaded with features, including power folding mirrors, blind spot monitoring, heating elements, and integrated turn signals depending on trim level.
The more features you have, the more things there are to fail—and mirrors on these trucks are a prime example.
Vehicle Concern
The concern started with the driver-side mirror feeling loose and appearing to overextend when folding outward.
After further testing, both mirrors would:
Fold in and out as commanded
Make a popping or clicking noise
Continue popping for 3–5 seconds after reaching the end of travel
That last symptom is the key detail most people overlook.
Initial Inspection
First step in any good automotive troubleshooting process is to verify the complaint.
We cycled both mirrors multiple times and observed:
Full movement in both directions
No hesitation or binding during travel
Audible popping after movement stopped
We also physically checked the mirror housings. Neither felt completely loose, which initially made it seem less like a mechanical failure.
That’s where a lot of techs—and DIYers—start heading down the wrong path.
Codes (If Applicable)
No fault codes were present in the system.
That’s important to understand:
Not all failures will set codes, especially when dealing with mechanical components driven by electric motors.
Diagnostic Process
At this point, it was time to determine whether this was:
A calibration issue
An electrical/control issue
A mechanical failure
Step 1: Relearn Procedure
These mirrors use a basic stall-detection system to determine end positions. There are no position sensors—just current monitoring.
We performed the standard relearn:
Fold mirrors fully inward and hold switch
Fold mirrors fully outward and hold switch
Repeat several cycles
Result?
No change.
The mirrors still popped after reaching their limits.
Step 2: Analyze the Symptom
Here’s where experience matters.
If a mirror:
Moves normally
Reaches full travel
Continues making noise after stopping
That tells you the motor is still trying to drive after the stop point.
That’s not a programming issue—that’s a mechanical feedback problem.
Step 3: Understand How the System Works
These mirrors rely on resistance to tell the module when to stop.
When everything is healthy:
Mirror hits a solid stop
Motor current spikes
Module shuts off motor
When something fails internally:
The stop is no longer solid
Gears slip or flex
Motor doesn’t see a clean spike
It keeps driving → pop, pop, pop
That’s exactly what we were hearing.
Key Findings
After repeated testing and ruling out calibration:
Both mirrors exhibited post-travel popping
Noise lasted several seconds after movement stopped
Condition was worse when extending outward
No electrical faults or communication issues present
This pointed directly to internal mechanical failure.
Final Diagnosis
Both power folding mirror assemblies have internal gear or stop mechanism failure, causing the actuator to slip at end of travel.
This prevents proper stall detection and results in continued motor operation and popping noise.
Recommended repair: Replace both mirror assemblies.
Common Causes
This is not a rare issue. In fact, it’s one of the more common problems seen on these trucks.
Typical causes include:
Worn or stripped internal gears
Broken plastic stop tabs
Weak or failed pivot detents
Frequent use of auto-fold feature accelerating wear
Once the internal components start to fail, there’s no reliable repair. These mirrors are not designed to be serviced internally.
Lessons for Buyers / DIYers
This is where this case really pays off—especially if you’re into used car inspection tips.
Problems like this are easy to miss unless you know what to look for.
If you’re checking out a truck like this:
Always cycle the mirrors fully in and out
Listen for any popping or clicking after movement stops
Don’t assume “it just needs a relearn”
Check that features like blind spot indicators are present and working
Mirror assemblies on these trucks aren’t cheap—especially with all the options built in.
Catching this during a pre-purchase inspection can save you a significant repair bill.
And if you’re diagnosing car problems yourself, this is a perfect example of why understanding system operation matters more than just swapping parts.
Don’t Get Burned on Your Next Used Car
If you’re thinking about buying a used car—or even if you already have one—this is exactly the kind of problem that can slip through the cracks and cost you big money later.
After 35+ years in the automotive field, I’ve seen firsthand how often people end up with vehicles that have hidden issues just like this.
That’s why I put together a simple Used Car Guide to help you understand what to look for and how to avoid making a costly mistake.
It’s a quick, practical guide designed to give you the right mindset and approach before you buy.
