Passenger side mirror replacement takes 15 to 45 minutes and costs $150 to $500 depending on whether you replace just the glass, the whole mirror housing, or both
The job breaks into three separate tasks: removing the old mirror, installing the new one, and reconnecting the wiring if your mirror has power adjustment or heating. You can do all three yourself with basic tools, or you can replace only the glass if the frame is still good. The cost difference matters: a replacement glass panel runs $30 to $80, a full mirror assembly runs $150 to $400, and labor at a shop adds another $100 to $200.
Before you start, identify what is actually broken. If only the glass is cracked or missing, you can buy a replacement glass insert and snap it into your existing frame — this is the cheapest and fastest fix. If the frame is bent, the motor is dead, or the whole assembly is damaged, you need a full replacement mirror.
Key Takeaways
- Replacement glass inserts cost $30 to $80 and take 5 to 10 minutes to install if your mirror frame is intact.
- A full mirror assembly costs $150 to $400 and requires disconnecting the wiring harness before removal.
- You will need a screwdriver set, possibly a trim removal tool, and a socket wrench depending on how your mirror is bolted down.
- Power mirrors require you to unplug the wiring harness inside the door panel before you remove the mirror.
- Most passenger mirrors bolt on from inside the door, so you remove the interior door panel first to access the bolts.
Replacing just the glass if the frame is still good
If your mirror frame is straight and only the glass is broken, buy a replacement glass insert that matches your vehicle year and model. These come as a flat pane with a backing, and they snap or glue into the existing frame. Check your owner's manual or search your vehicle's year, make, and model plus "replacement mirror glass" to find the right part.
Remove the old glass by gently prying the edges with a plastic trim tool or old credit card. Work slowly around the perimeter so you do not crack the frame. Once the glass is out, clean any old adhesive or clips from the frame. If the new glass has adhesive backing, peel and stick it into place, pressing firmly for 30 seconds. If it uses clips, snap the clips into the frame grooves first, then press the glass in until it seats.
Test the glass for movement and make sure it sits flush with the frame. If you have a heated mirror, reconnect the wiring before you finish. This fix takes 5 to 10 minutes and costs far less than a full replacement.
Removing the interior door panel to access the mirror bolts
Most passenger mirrors bolt to the door from the inside, so you need to remove the interior door panel first. Roll down the window completely, then locate the screws or clips holding the panel. These are usually along the bottom edge, the leading edge near the door latch, and sometimes hidden under a trim piece near the mirror.
Use a screwdriver or trim removal tool to pop off any plastic caps covering the screws. Remove all visible screws. Then gently pry the panel away from the door frame, working from the bottom up. You will hear clips popping — this is normal. Once the panel is loose, carefully pull it away from the door and set it aside. You may need to disconnect a wiring harness for the power window switch or door lock before you can fully remove the panel.
With the panel off, you can now see the three or four bolts holding the mirror to the door frame. These are usually 10mm or 13mm bolts. If your mirror has power adjustment or heating, you will also see a wiring harness plugged into the back of the mirror assembly. Unplug this harness before you remove the bolts.
Unbolting and removing the old mirror assembly
Once the wiring is disconnected, use a socket wrench or screwdriver to remove the bolts holding the mirror to the door. Most mirrors have three bolts arranged in a triangle or line. Keep these bolts in a small container so you do not lose them — you will reuse them for the new mirror.
Carefully pull the mirror assembly away from the door. It may stick slightly if there is weatherstripping or sealant around the base. Gently wiggle it side to side as you pull. Once it is free, set it aside.
Before you install the new mirror, check the bolt holes in the door frame. If they are stripped or damaged, you may need to use slightly larger bolts or have a shop drill and re-tap the holes. Most of the time the holes are fine and you can reuse the original bolts.
Installing the new mirror assembly
Position the new mirror against the door so the bolt holes line up with the holes in the door frame. If your new mirror has a wiring harness, plug it in first before you bolt the mirror down. This is easier than trying to reach behind the mirror after it is bolted in place.
Insert the bolts through the mirror mounting bracket and into the door frame holes. Tighten them by hand first, then use a socket wrench to snug them down. Do not over-tighten — you want them firm but not so tight that you crack the plastic mounting bracket. A good rule is to tighten until you feel resistance, then give each bolt one more quarter turn.
Once the mirror is bolted down, test the power adjustment and heating if your mirror has these features. Adjust the mirror to the correct position and make sure it does not rattle or move when you push on it.
Reinstalling the interior door panel
Slide the door panel back into place, starting at the top and working down. The clips along the edges will pop back into their slots. Once the panel is seated, reconnect any wiring harnesses for the power window or door lock. Then reinstall all the screws you removed, and snap any plastic caps back over the screw heads.
Roll the window up and down a few times to make sure nothing is pinched. Open and close the door to confirm the panel is find and does not rattle. If everything feels solid, you are done.

Frequently Asked Questions
Can I replace the mirror without removing the door panel?
No. The bolts that hold the mirror to the door are on the inside of the door, behind the interior panel. You must remove the panel to reach them. The only exception is if your vehicle has bolts accessible from the outside, which is rare on modern cars.
What if the bolt holes in the door are stripped?
If the holes are stripped and the bolts spin without tightening, you have two options: use slightly larger bolts with new holes drilled nearby, or take the door to a shop to have the holes re-tapped with a larger thread size. A shop can do this in 30 minutes for $50 to $100.
Do I need to disconnect the battery before I start?
It is not required, but it is safer. Disconnecting the negative battery terminal prevents accidental short circuits when you unplug the mirror wiring. If you skip this step, be careful not to let the wiring harness touch metal parts of the door frame while the mirror is out.
How do I know if my mirror is power-adjustable or heated?
Look at the back of your mirror assembly. If you see a wiring harness plugged in, the mirror has power features. Check your owner's manual or look at the mirror controls on your door panel — if there is a joystick or buttons labeled "mirror", your mirror is powered.
Can I buy a used mirror instead of a new one?
Yes. Used mirrors from a salvage yard cost $50 to $150 and work just as well if they are not damaged. Make sure the part number matches your vehicle year and model, and test the power adjustment and heating before you leave the yard if those features are present.
