Got a busted sunroof motor? Yeah, I’ve been there. The good news is you can totally handle this yourself. The motor’s hiding up under your overhead console—once you get in there, it’s really just unplugging some wires, unscrewing a few bolts, and swapping in the new motor. Most folks knock this out in a couple hours with whatever tools they’ve got lying around.
Honestly, fixing your sunroof doesn’t need to be this huge stressful thing. You don’t need to drop a ton of cash at the dealer or spend your whole Saturday cursing at your car. I’m going to show you exactly how to replace a sunroof motor without all the confusing jargon. Before you know it, you’ll be back out there with the wind in your hair, wondering why you didn’t do this sooner.
What Is a Sunroof Motor?
So what exactly is a sunroof motor anyway? Think of it as this little electric motor chilling up in your car’s roof. It’s got gears and cables that work together to slide that glass panel back and forth on its tracks. Hit the button, and boom—electricity fires up the motor, things start spinning, and your sunroof glides open. But when that motor dies? Yeah, your sunroof’s not going anywhere.
Most cars these days run on what’s called a worm gear system. It’s pretty clever, actually—strong enough to handle a heavy chunk of glass but small enough to fit up there without taking up a ton of space. The problem is, nothing lasts forever. Those gears inside start grinding down after a while, or sometimes the electrical parts just fry out. And when that happens, there’s really no quick fix. You’ve gotta do a full sunroof motor replacement to get everything working again.
Tools Needed to Replace a Sunroof Motor
You do not need a full mechanic’s shop to fix sunroof motor issues. However, having the right gear makes the job much smoother. Make sure you have these items ready before you start:
Tool Name | Purpose |
Trim Removal Tools | To pry off plastic covers without scratching them. |
Screwdriver Set | Both Phillips and flat-head for various screws. |
Torx Bit Set | Most car makers use T25 or T30 Torx bolts for motors. |
Socket Wrench Set | For removing larger bolts holding the assembly. |
Multimeter | To test if the motor is actually getting power. |
Flashlight | To see inside the dark gaps of the headliner. |
Step-by-Step Guide | How to Replace a Sunroof Motor
Before you begin, park your car on a flat surface. Make sure the glass is closed if possible. If the glass is open, you may need to manually move it later.
1. Disconnect the Battery
Safety comes first. Always unhook the negative terminal of your battery. This stops any electrical shorts. It also prevents the sunroof from moving while your fingers are near the gears.
2. Remove the Overhead Console
The motor is often behind the lights and buttons on your ceiling. Use a plastic trim tool to gently pop out the console. Be careful not to snap the plastic clips. Unplug any wires for the lights or the sunroof switch.
3. Lower the Headliner
You do not need to take the whole ceiling down. Just lower the front edge. You might need to remove the sun visors and the side pillar trim. This gives you enough space to reach the motor.
4. Locate and Unbolt the Old Motor
The motor is a small silver or black box. It is usually held by three or four bolts. Use your Torx or socket wrench to remove them. Keep these bolts safe as you will need them for the new part.
5. Swap the Motor
Unplug the wire harness from the old motor. Take the new part and plug it in. Line up the gears of the motor with the cables in the roof. This is a vital part of how to replace a sunroof motor correctly. If the gears do not line up, the glass will not move.
6. Test and Reassemble
Hook the battery back up. Tap the switch to see if the motor moves the glass. If it works, put the headliner and console back.

How to Fix a Sunroof Motor Without Replacing It
Sometimes the motor is not the real problem. Before you buy a new part, try these simple tips to fix sunroof motor glitches.
Check the Fuse
If the motor makes no sound, check the fuse box. A blown fuse costs pennies to fix. Use your owner’s manual to find the right one. If the metal strip inside the fuse is broken, swap it out.
Clean and Lubricate the Tracks
Dirt and old grease can get thick like glue. This makes the motor work too hard and eventually stop. Use a vacuum to pull out leaves and dust. Apply a thin layer of silicone-based grease to the tracks. This often brings a “dead” motor back to life.
Perform a Reset
Many cars need a reset after a power loss. Hold the “Close” button for ten seconds. The glass might move back and forth. This tells the computer where the limits are. This simple sunroof motor fix saves many people a trip to the shop.
DIY vs Professional Sunroof Motor Replacement
Deciding to replace sunroof motor parts yourself depends on your comfort level. There are pros and cons to both choices.
Doing it Yourself (DIY)
The biggest win here is saving money. You only pay for the part. You also learn a lot about your car. However, modern cars have side-curtain airbags in the roof. If you are not careful, you could damage these or the headliner.
Hiring a Pro
A pro has the right tools for every car. They also give you a warranty. If the sunroof leaks later, they fix it for free. This is often the best choice for luxury cars with complex panoramic roofs.
How Much Does It Cost to Replace a Sunroof Motor?
Costs vary based on your car’s make and model. Here is a look at what you might pay in 2025.
- Parts Cost: A new motor usually runs between $80 and $250.
- Labor Cost: A shop will charge for 1 to 3 hours of work. This adds $150 to $400 to the bill.
- Total Price: Expect to pay between $250 and $650 for a standard sunroof motor change.
If you have a large panoramic roof, the price can go much higher. These systems are heavier and harder to reach.
