2019 Dodge Ram 1500 Laramie Tailgate Not Consistently Lowering Fix

You’re dealing with a 2019 Ram 1500 Laramie tailgate that activates but doesn’t consistently drop down. This is a moderate fix mostly tied to the tailgate actuator motor or latch assembly sticking or failing. Safety-wise, be sure the truck is parked on level ground and the tailgate is supported when testing or working on it.

What you'll need

• Tools: Ratchet with 8mm and 10mm sockets, flathead screwdriver, trim panel removal tool, multimeter (for electrical checks), flashlight
• Parts & consumables: Tailgate actuator motor (most common failure), tailgate latch assembly (if actuator is good), white lithium grease or similar lubricant spray
• Optional: Tailgate control module (rare, only if electrical diagnosis points here)

Step-by-step

1. Check for obvious obstructions or damage to the tailgate and latch area. Dirt, rust, or debris can cause sticking.

2. Operate the tailgate switch and listen for the actuator motor noise. If no noise, suspect actuator motor or electrical issue.

3. Remove the tailgate trim panel to access the actuator and latch assembly. Use trim tool and 8mm socket to remove screws.

4. Inspect the actuator motor and linkage for signs of wear, damage, or binding. Manually move the latch to check for smooth operation.

5. Spray white lithium grease on the latch and actuator pivot points to lubricate.

6. Test the actuator motor by applying 12V directly (if comfortable) to see if it operates smoothly.

7. Check wiring harness and connectors for corrosion, loose pins, or damage that could cause intermittent power.

8. If actuator motor is faulty or fails the direct power test, replace the actuator motor.

9. If actuator motor is good but tailgate still inconsistent, inspect and possibly replace the latch assembly.

10. Reassemble trim panel and test tailgate operation multiple times to confirm fix.

Specs & resets

• Tailgate actuator motor mounting bolts: torque to 7 Nm (62 in-lbs)
• Use Mopar-approved white lithium grease or equivalent for lubrication
• No special reset procedure needed after actuator or latch replacement
• Electrical connectors: ensure clean, tight fit; use dielectric grease to prevent corrosion

Common mistakes to avoid

• Skipping lubrication: Dry latch or actuator pivots cause sticking and premature failure
• Ignoring wiring checks: Intermittent electrical faults often cause inconsistent operation
• Over-tightening actuator bolts: Can damage plastic components or cause binding
• Not supporting tailgate: Tailgate can drop suddenly causing injury or damage during testing
• Assuming actuator is bad without testing: Sometimes latch or wiring is the culprit
